Yama's is excellent! The sushi is great and the prices are very reasonable. For lunch you can order from a selection of "lunchboxes", which are combos of different things on the menu. For instance, the lunchbox I always get has tuna, salmon, whitetail, a california roll, and tempura. It also comes with miso soup and a salad. You can also order any of the sushi a la carte if you don't like the combo options.
The atmosphere is wonderful too, the chefs greet you when you walk in and you can sit at a table and watch them prepare your food.
I highly recommend this place!!!
