I have been to Little Sheep Mongolian Hot Pot two times now and both experiences were decent.
My favourite item on their menu is the shrimp as it was very fresh. The homemade fish balls and shrimp balls were not very good however. They fell apart easily and were mushy in texture. Everything else such as the beef, lamb, pork and veggies were good, but typical.
The service in my opinion was exceptional for a Chinese place, as the servers were very polite and helpful. Food came out quickly and our drinks were always refilled without having to ask. However, the place was very empty during my last visit, so that may explain why I had such attentive service.
They were also doing a promotion where you get bottomless soy milk and plum juice for free if you pay in cash. I thought that was a pretty sweet deal!
