Tibetan foods are totally different than Indians.
My recommendation is Tukba the noodle soup, they have spicy and non spicy version. it's really yummy. their foods are all yummy tho.
Staffs speaks English so please double check for milk, egg, butter etc. as they serve meat, they better get notice and be careful.

We went to this Restaurant today for lunch, it's up stairs on one of the alleys in Myeondong. It looked nice when we came in and when we looked at the menu it had a lot of vegetarian options.

We ordered the vegetable momos (dumplings) which were okay, just steamed with some dip. The main we ordered was the Thuk something (I think it was the dish the other reviewer had) It was meant to be noodles with vegetables in a red spicy sauce. The noodles were a mixture of cooked and not cooked - some crunchy. The mixed vegetables was just onion and some mushrooms, and the sauce was bland and not spicy at all. It was cold in some areas and hot in others. To be honest I'm pretty sure it was just chucked in the microwave.

Considering the 2 dishes cost us over 20,000 won, we were super disappointed and ended up getting a second lunch to make up for it.

The staff spoke english and the menu was in english which is good I suppose, but I definitely wouldn't go back again.
