The Rolling Pot is a Shabu Shabu restaurant (apparently the term Shabu is Japanese for the swishing sound when you stir the soups). This is not really a buffet restaurant but I can't imaging anyone not being stuffed afterwards.
Essentially you order a soup flavour, then pick multiple options for meats, veggies, noodles and other stuff to mix in it. Each table has a small cooking surface and you cook and eat your food.
Many side dishes and drinks are available.
Location is prime so parking is often at a premium here.
