Miz En Bouche
Time Out says
This French restaurant in Clerkenwell takes its name from the French term for 'appetiser', though we detect a hint of poetic license at play: strictly speaking it's mise en bouche. But we're not pedants and it doesn't really matter anyway – the bistro food here goes the full three courses.
Expect, then, French classics such as foie gras terrine, escargots à la Bourguignonne, hand-cut steak tartare and a cassoulet of confit duck leg, Toulouse sausage, bacon and beans. And if you fancy a burger? No problem – it's served in a brioche bun with French cheese and with French fries, of course. Each of the exclusively-French wines are available by the glass, carafe and bottle, bar one red and one white.
It's close to Sadler's Wells, so there's what looks like a good-value pre-theatre menu too.
