Bocconcino Mayfair, the original restaurant on Berkeley Street a few minutes from Green Park: regional Italian cooking built around fresh fish and seafood, with an open-fire pizza oven and a glass-fronted pasta station. Two floors, two evenings — white tablecloths and full service upstairs, a casual lower floor with DJs and live performers and private dining rooms. Open Monday to Saturday 12pm–12.30am, Sunday 12pm–10.30pm.
