I must say, Little Sheep is an excellent choice for casual hot pot. You can order either 1 large hot pot or a small individual hot pot, and the soup base costs extra. There's a selection of cold spring rolls and manto in the sauce area, and you can drink either soy milk, sour plum juice, and iced lemon water.
You can order three rounds of dishes to put into your hot pot, and the soup heats up quickly so that you don't have to wait for long. The atmosphere itself is rather quiet during the afternoon, but I can imagine it being a hot spot for dinner. The lunch AYCE costs around $20 per person after you add in the money you spend for the soup!
Favourites: cold spring rolls, sweet soy milk, garlic beef
Dislikes: garlic chicken (ugh)
