A simple space on the first floor of the Town Hall Hotel in Bethnal Green gives little away, but look a little closer and it becomes apparent that someone has a sense of humour: a spiral staircase leading nowhere; lamps hung at spectacularly varying heights; no external telephone. The place is unassuming. The menu is the same. Three ingredients are listed for each dish, with no indication as to how they’re to be prepared or served. Portuguese chef, Nuno Mendes – who trained at El Bulli – is best known for working his magic at Michelin-starred Viajante, downstairs, so as you settle into your seats at Corner Room you feel like you might just be in for a treat. And you’re not wrong there.
