7 Restaurant Social Media Case Studies, By the Numbers

Restaurant social media advice is everywhere. Verified numbers are not. Every case in this round-up carries a real, attributable metric — an SEC earnings exhibit, trade press quoting named executives, dated national reporting, or, in one clearly labelled case, our own first-party experiment. They run from a chicken sandwich that ended up in SEC filings to a chocolate bar that emptied UK supermarket shelves.

An honesty note before the numbers: five of these seven stories involve big chains or a once-in-a-lifetime viral moment. Only one — a pizzeria in Lambertville, New Jersey — looks like the independent restaurant most readers actually run, and our own bakery experiment at the end shows what a small operator can expect without going viral. So each case ends with the mechanic worth copying rather than the vanity number. This is also the restaurant deep dive of our case-studies series: the case-studies hub already tells five cross-industry stories — from Lay’s and Chipotle’s lid-flip challenge to Sephora and Glossier — so this post deliberately tells a different Chipotle campaign and keeps everything else in food service.

The playbook is older than TikTok, too. By mid-2009, the Kogi Korean BBQ truck in Los Angeles had 36,000 Twitter followers, per Wikipedia — enough to move crowds across a city with announcement tweets. Platforms change; the mechanics underneath — scarcity, participation, craft on camera — keep repeating.

The seven cases at a glance

Why the tiers matter: an SEC exhibit is a public filing a company can defend in court; trade press quoting a named executive is a company claim on the record; a secondhand figure is labelled as such and downgraded accordingly. When a consultant pitches you a case study with no visible tier, the tier is the first thing to ask about.

Case 1: Popeyes — the chicken sandwich that shows up in SEC filings

On August 12, 2019, Popeyes introduced a fried chicken sandwich to its menu, per Wikipedia’s account of the chicken sandwich wars. The weeks-long rivalry argued out on social media that followed is what makes this the rare social media story you can verify in financial filings rather than press releases.

In its Q3 2019 earnings release, parent company Restaurant Brands International reported Popeyes US comparable sales up 10.2%, with CEO Jose Cil saying Popeyes “had one of its best quarters in nearly two decades, achieving comparable sales growth of more than 10% in the US.” The sandwich quarter was bigger: the Q4 2019 release shows worldwide comparable sales up 34.4% against 0.1% in Q4 2018 — and up 37.9% in the US market — along with system-wide sales of $1,327 million against $934 million a year earlier, and a headline bullet crediting “transformational system-wide sales growth of over 42% in Q4 boosted by the Chicken Sandwich.”

The mechanic to copy: launch something the internet can argue about — a product with a confident opinion attached — and let scarcity finish the marketing. You will not post your way to 34.4% comps; Popeyes combined the buzz with operations. But a sandwich whose scarcity became the story is a social campaign with a revenue line attached.

Case 2: Chipotle’s #GuacDance — 250,000 videos in six days

The hub’s Chipotle case is the #ChipotleLidFlip challenge; this one is deliberately different. Just ahead of National Avocado Day on July 31, 2019, Chipotle ran #GuacDance, a TikTok challenge built on a guacamole dance meme. Writing in QSR Magazine in January 2020, Rachel Pittman reported that the challenge “was TikTok’s highest-performing branded challenge in the U.S., resulting in 250,000 video submissions during the six-day challenge and Chipotle’s biggest guacamole day ever, with more than 800,000 sides of free guac served.” (The magazine’s site now sits behind an access gate for some readers; we verified the figures against the archived copy.)

For comparison, the lid-flip challenge told on the case-studies hub “generated more than 100 million views and a record-breaking digital sales day,” as Restaurant Business reported.

The mechanic to copy: participation, not perfection. Give people a dance, a dare or an easy-to-copy format, attach a dated hook (a food holiday) and a free-food reward, and the audience makes the ads for you.

Case 3: Dunkin’ and Charli D’Amelio — 57% more app downloads in a day

In September 2020, Dunkin’ put a Charli-branded cold brew drink on the menu with Charli D’Amelio, then one of TikTok’s biggest stars. The company’s own figures, reported by Restaurant Business on October 2, 2020: launch day drove “a 57% increase in Dunkin’ app downloads in comparison to our previous 90-day average,” in the words of VP of brand stewardship Drayton Martin; “hundreds of thousands” of The Charli sold in the first five days; and cold brew sales up 20% the first day and 45% the next.

The mechanic to copy: the partnership worked because the product was the campaign — a real drink built around a creator’s name, not a scripted ad read. And notice the measurement: a percentage lift against a stated 90-day baseline. Decide the metric and the baseline before you spend, and hold the campaign to it afterwards; a number like “57% more app downloads” only means something because the denominator was fixed in advance.

Case 4: Liberty Hall Pizza — 8 million views from one wood-fired oven

The independent-restaurant proof. Liberty Hall Pizza in Lambertville, New Jersey, is the counterpoint to the big-brand budgets: kitchen manager Brandon Murphy “has accumulated more than 200,000 followers with fairly straightforward videos of himself making pizza in the restaurant’s wood-fired oven,” and his first post, from February 2020, “has more than 8 million views,” according to the same Restaurant Business report.

The mechanic to copy: film the craft you already have. Fire, dough, steam, the plating at the pass — a working kitchen is a content studio. The binding constraint is format consistency, not production value.

Case 5: baked feta pasta — the recipe that emptied cheese aisles

In January 2021, a baked feta pasta recipe video by @grilledcheesesocial spread across TikTok until, as FOX 5 New York reported that March, retailers saw feta cheese sell out — a shortage sparked by home cooks, not by any brand’s campaign. For scale, Wikipedia states that “feta cheese sales soared by 200% in 2021 after the baked feta pasta recipe took off” — a figure attributed to the New York Times and, as far as we could verify, relayed only by Wikipedia; treat it as secondhand.

The mechanic to copy: nobody owned this trend, and that is the point. When a dish goes viral in home kitchens, the play is to put your version on the menu while the search volume is still climbing. Speed beats polish.

Case 6: Fix’s Dubai chocolate — 122 million views, 30,000 orders

The freshest case in the set. A taste-test video by influencer Maria Vehera — 122 million views, per The Guardian — turned Fix Dessert Chocolatier, a small Dubai brand, into a worldwide craze. Founder Sarah Hamouda said the company received “more than 30,000 orders” after the video went up — in a New York Times interview relayed by The Guardian; when Lidl launched its own bar in the UK at £4.99, it sold out; and by 2024 the bars topped Deliveroo’s most-popular-orders table.

The mechanic to copy: be filmable. A thick, pistachio-filled slab that breaks open on camera is a natural for vertical video, and the creator’s video — not a brand campaign — did the selling. A product designed to look good being broken open is a social media strategy.

Case 7: our own bakery experiment — the realistic numbers

Finally, the first-party case, labelled as such: our own experiment with a bakery in Ljubljana. Using Picmim to draft and schedule the owner’s posts, engagement rate rose from a 2.1% previous average to 3.2% in week one (13 posts published, 25 minutes of the owner’s review time) and 3.8% in week two (18 minutes of review time). No viral moment, no paid spend, no third-party audit — which is exactly why it sits last and the externally verified cases above carry the credibility load.

The mechanic to copy: consistency. Two steady weeks of on-brand posts moved the number further than any single clever video would have.

How a restaurant applies all of this

Mapped to decisions rather than admiration:

• Launch something arguable. A menu item with a story or a stance, then scarcity and replies do the rest (Popeyes).
• Invite participation with a concrete hook. A format customers can copy, a food holiday, a free-side reward (#GuacDance).
• Partner where the product is the content. A local creator’s actual order, named after them, with a pre-agreed metric and baseline (Dunkin’).
• Film the craft you already have. The oven, the dough, the plating, on a repeating format (Liberty Hall).
• Answer home-cooking trends fast. A viral dish on your menu this week beats a polished campaign next month (feta pasta).
• Make the product filmable. Texture, break, layers, colour — design at least one item that wants to be recorded (Dubai chocolate).
• Show up every week. Repeated, on-brand posting is the only mechanic here that needed no luck (our bakery).

If you want working starting points, the blog already has a 7-day social media plan for restaurants, a restaurant Instagram content strategy, and a bank of social media ideas that fill tables; food trucks have their own guide. And if time is the constraint, we have written about how restaurants use AI for social media and how restaurants use AI to fill tables through social media.

One caveat to carry out of this list: the mechanics repeat, but the metrics are snapshots. Reach numbers from 2019 or 2021 TikTok do not price 2026 attention; treat every number above as evidence that a mechanism worked once, at scale, somewhere.

The five cross-industry stories that complete this series — Lay’s Do Us a Flavor, Chipotle’s lid flip, Sephora’s Virtual Artist, ASOS’s #AsSeenOnMe and Glossier’s community playbook — are on the case-studies hub.
