The momos -- whether they're the tongue-tingling chili variety, the carefully pleated Himalayan dumplings, or the moneybag-shaped fried firecrackers dressed in a tangy sauce -- merit a trek to this Tibetan BYOB, appropriately nestled high on the hills of Roxborough. Chef-owner Treley Parshingtsang has many other tricks up her sleeve, including a spicy glass noodle salad, coins of handmade Tibetan sausage that melt in your mouth, "Shangri-La style" zucchini in a sweet-and-sour sauce, and thenthuk: hand-pulled noodles swimming in a gingery, tomato-infused beef broth. The experience is enriched by the soft-spoken, attentive service in the cozy golden dining room adorned with candle-lit windows.
