Lhasa Fast Food is a favorite stop on my Himalayan Heights Food Tour. Tucked away behind a cell phone store, it’s a veritable Shangri La of Tibetan cooking and home to my favorite beef momo. Juicy and scented with Sichuan peppercorn, it’s well worth the wait. The momo speakeasy is also home to a secret off-menu dumpling: Chu-tse momo, or beef and chive momo. Chu-tse momo are a lighter, greener alternative to the beef variety.
