The food was good, lots of salads, traditional japanese ingredients, some soy meat options, rice. But there was one dish with fish (let them tell you what includes 'sakana').
Unfortunately the buffet featured only cold dishes and nothing really warm (apart from the fish soup!). :( And for a cold buffet I thought that 2100 Yen was a little much.
Also: the soy chai latte was not traditional chai. It had a lot of lemongrass in it and tasted a little "unexpected". ;)
But if you're good with a cold buffet (except for the rice apparently) then it's a good place, if you can spend a bit more.
P.S.: None of the cookies were vegan, unfortunately. :(Pros: Good taste, All you can eat, Nice staff
Cons: Only cold buffet (as I was there), No vegan cookies, A little expensive
