Situated on Warren Street, a veritable no-man's land known only for its reputation as a source of cheap Viagra, Mushu was opened in 2010 by an ex-City couple with an enthusiasm for clean, healthy Oriental food. The premise is simple and not terribly original - unfussy, honest food served up in simple surroundings. Think Wagamama-style Asian-fusion, but on a much smaller (and tastier) scale. A bright, no-nonsense, fit-for-purpose room, the kitchen and prep areas are visible from the dining areas, so Mushu patrons can whet their appetites watching the culinary magic taking place before their eyes. Evening diners going for relaxed Izakaya-style dining might want to stick to the long benches, since the stools aren't the height of comfort, although once you've washed down a cup of warm sake or a glass of their excellent Pinot Grigio you probably wont notice. The tasting menu provides the opportunity to sample the breadth of Mushu's well-priced culinary repertoire: the house speciality is the Water and Potsticker dumplings, with fillings that included Korean spicy beef and Kimchi and a homemade Szechuan garlic sauce guaranteed to spark your tastebuds. Also highly recommended is the melt-in-your-mouth Nasu Dengaku, a grilled Aubergine finished with sweet miso sauce. If the original purpose of the Izakaya is to fill the hunger gap created when drinking sake - and doing it in an environment that might encourage you to drink more sake - then Mushu fits the bill: well worth the trip to the depths of Fitzrovia.
