The BEST place to get hot pot (or shabu) in Cleveland. You can do family style or your own pot, and it's all-you-can-eat. The options for hot pot are more extensive at night, and I would recommend going for dinner.
If you've never done hot pot before, I would go with someone who has, preferably someone Chinese. I can understand how it wouldn't necessarily impress you if you don't know how to mix the sauces, or pick out only "safe" meats and veggies, or if you overcook the hot pot. This place is legit - no further evidence is needed than all the hoards of Asians at the hot pot tables.
(PS) My husband did their all you can eat sushi. It was good, but to me, sushi isn't what makes this place special.
