Hawaiian poké brand Honi Poké is to open its second site near London's Fenchurch Street on 7 March.
The 65-cover, 2,150 sq ft restaurant will serve breakfast, lunch and dinner Monday to Friday.
The menu will include four signature protein bowls created by founder Vladimir Martynov and executive chef Richard De La Cruz (formerly of Spain's two Michelin-starred Sergi Arola and three Michelin-starred Quique Dacosta restaurants).
The bowls come with a choice of flame-torched octopus, tuna, salmon, teriyaki chicken or tofu; paired with sushi rice, brown rice or veg slaw and a house-made, gluten-free sauce.
Diners can also choose to customise their bowls with protein and ingredients such as salty mango, sunomono cucumber and nori seaweed from £7 per bowl.
For breakfast, fresh house smoothies and coffees are served from 7.30am alongside popular South American tapioca bread, made with cheese and gluten-free flour, and scrambled or poached eggs on toast with cream cheese and avocado, or smoked salmon and dill.
Martynov said: "Since opening our debut site on Soho's Dean Street this time last year, we have developed a fantastic following and are incredibly excited to take the next step on our journey. Fenchurch is a much larger site, allowing us to trial breakfast and serve alcohol to the city crowd on our doorstep."
