Although Soya calls itself Japanese, the cuisine in this hidden courtyard restaurant just off Mariahilferstrasse can be best described as Asian fusion. In addition to sushi platters, bento boxes and noodle soups, some Chinese and Thai dishes are also served, and the reasonable prices, including occasional half-price sushi sets, explain why it's hard to find a seat here at lunchtime. A cosy garden nicely complements the small premises.
