The group, from family members Manami and her sons Louis and Leo Sloley, already has one site apiece in South Kensington and Soho.
The 40-cover Fitzrovia site at 4 Windmill Street will serve a poké menu inspired by modern Japanese cuisine, and all dishes will be created using high quality sashimi-grade fish from Japanese suppliers Atariya.
Typical options will include the ‘Classic Poké’, which comes with salmon or tuna, sesame soy, spring onion, edamame, sesame seeds and nori; and Kaisen Poké (the bestseller at Tombo Soho) includes ponzu citrus soy, salmon and tuna, edamame, avocado and nori.
A meatier choice will be the teriyaki chicken ‘poké’ served on with rice or courgette noodles, while there is also the ‘Tombo’s Vegan Special’ for vegans.
There will be a ‘build your own poké’ option, allowing customers to mix and match ingredients from a selection of bases, mains, toppings, and sauces such as wasabi soy, sriracha mayo, and ponzu.
Drinks will include the classic matcha tea – alongside a wider Asian-inspired selection ‒ while desserts will also focus on the bright green Japanese tea powder, with matcha tarts, matcha cheesecakes and matcha ice cream.
There will be a short beer and sake menu focusing on Japanese brands such as Asahi and Kirin Ichiban, alongside Japanese plum wine and bar snacks such as hijiki wakame salad and poké plates without the rice base.
Already popular in the USA, Hawaiian-born, Japanese-influenced poké has been a growing trend in London over the past couple of years. Other brands include Ahi Poké and restaurateur Kurt Zdesar’s Black Roe, as well as brunch favourite Granger & Co, which serves a tuna version.
