I mostly lurk here but I just have to rave about the new Annapurna Cafe on Broadway. They serve Tibetan, Nepali and Indian cuisine and everything I have had there is fabulous and unique. It's a little hole-in-the-wall kind of place without much in the way of ambience, and the service is extremely friendly and attentive but also unpolished. The food though is absolutely to die for.
I especially recommend their momos (steamed dumplings) which rate equal with the best momos I've ever had with a lovely cilantro-mint sauce on the side - these momos are not to be missed! Momos are addictive though, so watch out :)
Their curries are really good and their lamb tikka was also lovely. The blending of spices is quite unusual, hints of India and China and Russia... I highly urge you to check them out.
