Austan Loodust vegan buffet is upstairs at Mahemarket food store (around corner on Mustamäe tee and set back from the street; see other Happycow listing). I arrived too early for 12 noon (Friday) start, but at 11:40 the salad bar, the soup, bread and water (with slices of cucumber and lemon) were already set out. The soup and a piece of dark bread cost 2,60 euros. By noon the hot buffet was ready. Sold by weight.
There’s a large outdoor deck for good weather. Rough wood walls, warehouse-like, corrugated tin ceiling.
The buffet included green salad, potato salad, sprout salad, cole slaw, pasta salad; and hot items: pasta, bean patty (crumbly but with accompanying tzatziki-like sauce), roasted beets and yams, potato patty and extravagant-looking desserts. I bought a generous slice of apple cake and a cabbage-filled pastry roll to take away. The next day I warmed up the takeaway vegan quiche in an oven (not microwave), and it was really good and satisfying.
Cons: opens only at noon
