Vibrant, buzzy Oscar is an upbeat bar and restaurant with a chic Fitzrovia clientele and a modern British menu. Set in the charming Charlotte Street Hotel, this lively space is vivaciously decorated with colourful striped chairs and a dynamic mural of contemporary London by Alexander Hollweg. Inventive, vigorous dishes such as loin of venison with onion squash, chestnuts and blackberries and lemon sole with caper butter issue forth from the open kitchen.
