Yoma is a wonderful Burmese Restaurant located in the "vegan district" of Boston (i.e. next to Grasshopper and Piece O' Pie). While the restaurant itself is not all-vegetarian, it has many wonderful vegetarian and vegan options on the menu. My favorite Burmese restaurant staples are the Tea Leaf Salad and Coconut Rice, and Yoma does an excellent job with both. I especially love the fact that the Tea Leaf Salad comes "disassembled" so that customers can mix it themselves. The Burmese-style limeade is also highly recommended - it's not overly sweet, which makes it much more palatable than most American-style lime juice drinks.
Overall, I would say that Yoma is one of the better Burmese restaurants that I've been to. The food was delicious, the service was very quick and attentive and there wasn't a huge wait to get a table.
