First of all I don't like the whole individual pot thing. It takes away the fun of going for hotpot.
The way to judge hotpot is the soup base. I order the spicy and was very disappointed by it. Not only was it not spicy it was way too salty. The friends I went with complained of the same problem even those with non-spicy.
The cuts of meat provided were fine, but some of the vegetables, such as the carrots, were cut in odd shapes not very suitable to hotpot. Also no tofu skin left me very sad.
Little Sheep was never my first choice for hotpot when in China, but this place was not a good experience. No problems with the staff however who were fast and helpful.
