This week, Chris sits down with Victor Lugger, co-founder of Big Mamma and Sunday, to unpack how “invisible tech” (think: pay-at-table that just works) can lift guest experience, speed up service, and actually reduce the tech clutter on the floor. From 31 trattorias across 8 countries to Sunday now processing $4.2bn and hitting ~90% adoption in London, Victor shares the operator’s lens on what matters: faster, simpler payments; more time for hospitality; and real-world KPIs that move the P&L.

• Why “less tech, better service” wins: replacing terminals with phone-based payment, not piling on more tools.

• Adoption that sticks: 70% in months → ~85–90% in the UK when teams offer the option properly.

• Guest experience uplift: table turns +12–16% at busy brands; reviews surge when the Google prompt sits right after payment.

• Tips up, teams happier: 2–4× tips (UK) and ~+12% (US) thanks to AI-powered tip prompts.

• Loyalty that finally works in full-service: ~52% of Sunday payers enrol vs 2–5% on terminals; earn/burn becomes seamless.

• Enterprise scale: POS-agnostic (24+ integrations), terminals + pay-at-table + hybrid ordering where it fits.

• The “guest app” vision: payment as the universal touchpoint to identify 70–100% of guests and trigger CRM/loyalty, not just bookings.

• 59:30 Where to find Sunday & wrap-up

• “We’re not adding tech — we’re replacing old tech with something guests already have in their pocket.”

• “Give guests the option. If 82% choose phone, we’re doing something right.”

• “With Sunday, tips are 2–4× higher in the UK and about +12% in the US.”

• “On Sunday payments, ~52% of guests enrol to loyalty. On terminals it’s 2–5%.”

• “Dishoom Shoreditch went from ~10k reviews at 4.4 to ~38k at 4.8 in 18 months.”
