OVER DEZE AFLEVERING
The Stacked Podcast — where hospitality meets technology. Powered by Lightspeed.
Tonkotsu has gone from six sites to nineteen, with a twentieth opening in Bath, opposite the Roman Baths. Mike, the brand's finance director, has been there since 2017 — and along the way he picked up the systems too, because in a business this size somebody has to.
Chris sits down with him for an unusually honest conversation about what changing technology actually looks like when there's no CTO, no big central team, and no appetite for being sold a dream. Mike talks through the POS move to Lightspeed — one site, then four, then all of them — and what having live sales on every phone changed for his area managers and GMs. He explains how weekly stocktakes went from counting for counting's sake to a variance managed inside the week, how wastage got below 0.9%, and why his team still builds the rotas themselves rather than buying a platform that can't match what they've got.
There's a straight answer on AI too. Mike's seen invoice automation get rebranded as AI, likes what it might do for rotas, and has one warning worth the price of admission: be careful that AI doesn't become the accountant everyone used to blame for running the business off a spreadsheet.
Plus: the £1m electricity quote, the NI threshold, 20% EBITDA a decade ago versus fighting to stay flat, vibe-coded tools built by operators, and why if someone actually phones your restaurant you probably want to speak to them.
