Everest Momo is undoubtedly the king of momos of all times in ktm.Kalikastan momo is not far behind. The king momo chain was doing very well but it was gone last summer i was in ktm. I was extremely disappointed with the taste of sumai ko momo. In US, You should definitely try the Yak momo served in the tibetan restaurant in Northampton, MA. and Of course, the momos at the himalayan grill near new haven has been making quite a wave in recent times.
