Bumping my rating up to a 4 because I just tried a different broth (the herbal one) for the hot pot and it was delicious! It was enough to change my opinion of this place from "I'd only eat here out of convenience" to "I could see myself looking forward to coming here or recommending it to a friend".
So yeah, to reiterate: If you come here for hot pot, don't bother with the default broth they offer for hot pot. It's just a plain, clear, mostly flavorless broth. Definitely pay the $1 for one of the fancier broths!
