Thank you. Thank you thank you thank you. I'll let the other reviews talk about the cuisine. I'm not well-enough versed in Nepalese to really get into it. I will say this: the textures, the flavors, the quality of ingredients. Wonderful. Simply wonderful.
Please do not think my review (and the rare 4 stars) is because I live in a gastronomic desert. I do, I admit it. But the food here is absolutely wonderful. Not only that, but the size of the place, the hole-in-the-wall ambiance, and the cash-only policy allowed me to pretend, for half an hour, I was in New York City.
Your mom says you should eat at Himal Chuli, and so do I.
