The place was packed the day we went there. Small groups of college kids everywhere, drinking lots of alcohol and eating lots of food. It turns out all food and drink are 399 yen. Strangely enough, in addition to the Southeast Asian dishes, there were a lot of Mexican choices as well.
We had Vietnamese spring rolls, Pad Thai, and some sort of fried rice. Nothing was very authentic, or tasty. I would not come here again for Asian cuisine, there are too many better choices in Shimokita. I also felt that the kitchen was too cluttered, maybe it wasn't unclean, but it felt that way.
On the other hand, it is a really inexpensive, fun place to drink. There was nothing wrong with my margarita!
During the day, Taraato has an all-you-can-eat buffet with four sections: main, salad, dessert, and drink. I've never seen it, so I can't comment.
Address: Kitazawa 2-11-3. From the South exit of Shimokitazawa Station, take an immediate left down the street (toward Chazawa dori). It is a short walk down on the left.
