Dominic Hamdy and Oliver Hiam, who also launched London coffee shop Lundenwic in 2015, will open Crispin on 20 August.
The 70-cover café will occupy a custom-built zinc and glass pavilion on White’s Row, described as resembling an “origami-folded kite or bird”.
It will open daily from 7.30am, serving takeaway coffee and breakfast ranging from bacon sandwiches to ‘egg and soldiers’.
From 5pm Tuesday to Saturday the restaurant will offer a nightly dinner plate with a glass of wine for £10, alongside bar snacks, craft beers and cocktails.
There'll also be weekend brunch and a lunch menu with a daily soup and salad, and hot toasties such as cheddar, hispi cabbage and chilli jam.
Hiam, who runs his own record label Tessellate, will curate the playlist at the ‘listening bar’, where customers will be able to listen to his record collection through one of seven pairs of headphones.
Crispin will open in Spitalfields on 20 August serving £1 coffee all week from 7.30am, before officially soft launching with 50% off food after the Bank Holiday weekend.
