I will start with my sole complaint: the service is painfully slow and frustrating. As a frequent visitor to many hole in the wall type restaurants, I am quite patient with service but Himalayan Kitchen needs to hire another person in the front who actually knows the menu.
Get the momos - steamed. These are hands down the best things we tried. Try the Himalayan Kitchen special chow mein if you are a fan of the Singapore Rice Noodle (aka curry powder). The chilli potatoes were an addictive combo of slightly sweet, tangy and spicy.
The shabaley weren't my thing - there was a tiny bit of filling and a large amount of pastry. I rather have more momos.
They only accept cash or debit cards.
