Takê Sushi House

This restaurant has several branches in Campinas and the one I've gone several times is the one located in Barão Geraldo, at R. Maria Tereza Dias da Silva, 12. The ambience is nice, well lit, clean and fresh.
The buffet price is the average (about R$ 25 by July 06, 2012) and the beverages about R$ 3 R$ 4, with all-you-can-eat hot and cold dishes: Yakisoba, salmon, sushis, sashimis and also the dessert (condensed milk pudding or passion-fruit mousse).
Nevertheless, the place is not so huge so if don't get to arrive before noon, chances are you'll have to wait on the line a few minutes to get in. And when it's crowded the food is not prepared as fast as it's consumed, so you might end up by not getting what you want 'cos someone else may have taken the last piece
Anyway, IMHO it's worth checking it out!
