The Melting Pot is rather expensive - probably just as expensive as Ruth's Chris. I'd say it's worth it. The lights are dim, the music is soft and eclectic, and it's great for a date or couple's night. Plan on spending about $115 (without tip) per couple for a four-course meal with a 1/2 bottle of wine.
We had the Wisconsin blend cheese fondue - I thought it a bit sour and would try the spicy or cheddar blend next time. I had the California salad which was fabulous. We had a fancy broth fondue for our main course (though next time I think the regular broth one would've been fine) and the flaming turtle for dessert. All were absolutely excellent. Our service was also amazing.
I would not waste time on the veggies during the main course - stick to the protein and save room for the chocolate!
