Visited Shu at 12:30 and was surprised to find there was only 1 other table of diners inside. However by 1pm most of the tables were full and the restaurant had a lovely buzzy, busy atmosphere about it. The lunch menu is excellent value, starters and mains for £3 each and a main course for £8. The food was excellent, my highlights being the ricotta and blood orange starter, chicken and Parmesan polenta main and lemon tart dessert. Delicious!
