It's great to take friends to if you need some meat in the mix to satiate the group. The sampler was more than enough for me and my hungry sister. I'll try to swing by next time I'm in the area.
Vegetarians (and meat eaters), I highly recommend the Veggie Sampler (the Kik Ali-cha is particularly delicious) and the Ingudai Tibs (mushroom); The chickpea and potato dish is good, but not great.
The ordering/paying experience is a little strange and awkward for a pseudo sit-down restaurant: You order at the counter, hand them your credit card and then are handed the iPad to enter tip and sign
The vegetarian combo was OK. The paying process is awkward... Had to pay in advance, including tip. Service was slow, and the place is located where I would not recommend wondering around at night.
