Good things come in small packages. Yama-Q has a sushi bar and a simple dining room with about a dozen tables. Mainly Japanese with innovative use of vegetables and seafood, the menu changes regularly and is posted on a blackboard. You might call the cuisine healthy because there are lots of choices for vegetarians. Others might order duck quesadillas, agadashi tofu, seafood dumplings, buckwheat noodles in a broth of kelp and mushrooms, eel kabayaki, shrimp and vegetable tempura, banana tempura, or green tea ice cream.
