The last review, "nice suprise", is very close to that, what i want to say. Tao was the last place by the way through veg restaurant, which were all closed because of lunch break. Tao was too, but because of the prices, i decided to wait.
No stories anymore, but facts. Meal costed us 6,50 + 1,00 beer, so for two person it was 15e. It was a buffet plate with five dishes to choose (we were just after opening, so there was not to many, but later they made more; however you can also take smaller and cheaper plate). Everything was vegan and actually everything was great. We had very good seitan and perfect pumpkin mousse, nice tofu and well prepared lentiles. Tempura was also the right choose. One portion was totally enough.
I don't think that staff is not nice, they are just quite shy and asian-way calm, except one guy who speaks english and wich is very nice. Ok, it could look better inside, but if you know portugese pastelerias - it's pretty fitted into the city. I've spent very nice time there though and i'll come back there for sure.
Cons: for me - none
