I love Melting Pot too! I go there quite often with my girlfriends, and I brought my daughters there once. After trying the Big Night Out I have decided that I will only go there for cheese, chocolate, drinks and salads from now on. They do those VERY well, and they are delicious, and more than filling for a meal.
I'm another one who couldn't stomach the sight of raw meat. I'm a vegetarian, and I cooked my veggies in broth while my carnivore friends cooked their meat in oil, but it was enough to make me feel icky. They complained that it was hard to know when the meat was done.
But the cheese is unbelievable, and the chocolate is to die for! I was making inappropriate noises with that chocolate fondue. The drinks are incredible too. You will have a wonderful time! Our MP is very upscale and the service is fantastic. Have fun!
