We really enjoyed this place - one of the best kept secrets of state street is up sketchy staircase, much like city bar is down a sketchy staircase.
Their sauce bar is amazing with 10-15 different options to make your shabu shabu rock even a bit more. It was a lot of food and good variation of veggies for a decent price. I like this place much more than mini-hot pot on park. The dessert buffet is a bit sketchy though.
