Whether you are looking simply for a glass of wine or a substantial meal (or, indeed, both) then this is as good a place as any in Vienna. Serving many different wines from a number of producers (with a focus on organic and natural wines) Mast also offers some genuinely outstanding food, from substantial bar snacks to contemporary twists of classic Austrian food. The lunchtime set menu is a bargain. The venue itself reflects the young team's vision of food and wine: simple yet elegant.
