Attach rate: guests who add a dessert, second drink or side
What the answer looks like
Illustrative output on sample data
Illustrative example: how Lexi answers this for a sushi restaurant group with eight venues. It counts dinner checks from POS over the last quarter.
- Venue A: 14,000 checks, 3,920 with dessert. Dessert attach rate = 3,920 ÷ 14,000 × 100 = 28%. Second drink 46%.
- Venue B: dessert 12%, second drink 41%.
- Venue C: dessert 25%, second drink 23%.
What the data shows
Venue B lags on dessert and Venue C on second drinks, while Venue A leads on both.
What it means
Venue A's servers offer a dessert pairing with the check, and Venue C has no sake or wine list on the table.
What to do
Roll out Venue A's dessert pairing at Venue B, and add a drinks card to tables at Venue C.
Raising Venue B's dessert rate to 25% would add about $46,000 a quarter. Want me to show attach rates by server?
Attach rate formula
Why it matters
Add-ons lift the check without needing another guest through the door. Comparing attach rates for desserts, second drinks and sides by venue shows which teams sell them well, where the gaps are, and how much a small improvement would add across thousands of checks.
Frequently asked questions
What is attach rate in a restaurant?
Attach rate is the share of checks that include a particular add-on, such as a dessert, a second drink or a side. It shows how often guests add items beyond their main order, and it is one of the simplest ways to lift average check.
How can restaurants increase attach rates?
Make the add-on easy to say yes to. Suggest a specific pairing at the right moment, put it on the menu next to the main, and train staff with the venues that sell it best. Track attach rates by server to share what works.
Which checks count toward an attach rate?
Count only checks where the add-on makes sense, such as dinner checks for dessert, and exclude staff meals, comps and drinks-only tabs. Keep the same rule across venues and quarters, so the comparison stays fair over time.
