I think there was a post about Bui Natural Tofu before, but I think it listed an incorrect address. It's at 520 NE 76th Ave at Glisan.
I've been there twice I highly recommend it. All housemade tofus, like green onion tofu and lemongrass tofu. It's mostly a take-out place, but I think there are a few tables.
They say they are open to 7:30pm, but you should get there early because they often run out of the good stuff.
Other things on the menu include plain fried tofu, several things with pork (but I don't eat meat), and those round fried sesame balls.
