If you're looking for cheese-saturated burritos, you've come to the wrong place. Tu Y Yo is a Mexican fonda, which means it's rather like getting home cooking. You won't find dishes like this elsewhere in Boston, especially those stuffed with grasshoppers. For the more cautious, there are plenty of seafood, beef and chicken dishes and a smattering of tasty vegetarian dishes (the spinach potato one is especially recommended). Sangria, wine and beer. Very crowded on weekends.
