How Lettuce Entertain You built a 550,000-email database with sunday

A first-party database that compounds at scale

Guest data is one of the most valuable assets a restaurant group can build, and one of the hardest to accumulate without the right infrastructure. Lettuce Entertain You has collected 550,000 customer emails in just six months through sunday, creating a direct marketing channel that doesn’t depend on third-party platforms or paid media to reach its own guests.

At the individual venue level, each visit is a small contribution. Across 50+ restaurants, those contributions stack quickly. The result is a growing database that belongs entirely to the group, enabling direct communication, loyalty programs, and promotions that can be deployed at scale or targeted to specific venues and audiences.

sunday has been a valuable addition to our restaurants. It simplifies guest payments, helps our teams turn tables more efficiently, and supports the kind of hospitable experience we aim to deliver every day.

Half a million feedback signals, and counting

Alongside that email database, Lettuce Entertain You has captured over 486,000 individual pieces of guest feedback through sunday, giving the group a real-time view of the guest experience that cuts across every venue.

For a group of this size, that kind of visibility is genuinely difficult to achieve through traditional channels. Internal feedback arriving at the moment of payment, rather than surfacing days later via public reviews, gives management teams something they can act on immediately. Trends that would take weeks to identify through conventional reporting become visible in real time, across the whole portfolio at once.

Consistent operational gains across every location

Beyond data, sunday has delivered a consistent operational shift across Lettuce Entertain You’s venues. The group saves an average of 7 minutes per table, a gain that accumulates meaningfully over a full week of service across 50+ locations.

Staff benefit directly as well. A 22% tip rate on sunday transactions reflects a checkout experience that lands at the right moment and makes it easy for guests to show their appreciation. With 34% of guests paying through sunday’s QR code, the adoption is strong enough to have a tangible effect on the floor experience without requiring staff to push it.

At the scale Lettuce Entertain You operates, even incremental improvements per table become significant group-wide outcomes.
