Pizzakaya Roppongi

Pizzakaya is a Roppongi institution: an American-diner-style pizzeria that has been feeding Tokyo's international crowd craft beer and California pizza since 1996, now settled into a bigger room on the 2nd floor of the Sumitomo Fudosan Roppongi Grand Tower, a short walk from Roppongi-itchome Station.

The order to know is the gluten-free crust California pizza, built on a cauliflower base and topped, on request, with house-made cashew cheese instead of dairy, so a coeliac traveller and a dairy-free one can order the same pizza without either side compromising. The gluten-free line runs on a genuinely separate workflow rather than a token substitution: dedicated equipment, pizzas baked on parchment to limit cross-contact with wheat dough. That said, diner reports on cross-contamination aren't unanimous — most describe no reaction at all, a few mention lingering unease in what is still a compact kitchen — so anyone with a severe gluten allergy should say so clearly when ordering and let the staff talk them through it, rather than assuming "gluten-free menu" means "gluten-free premises."

The room leans hard into its American roots: booth seating, English-language chatter, ten rotating craft beers plus Californian wine, the kind of place that fills with homesick expats on a Friday night as easily as with visiting families hunting for a menu their kids can actually read. Staff speak English fluently and the menu is printed in English as standard, so there's no language friction at the table.

Practical note: online booking through Tabelog or TableCheck is the easiest way in, especially on weekend evenings when tables go fast; walk-ins are workable outside peak hours but not guaranteed.
