Recalling my 2 past visits here from a while back..
Good variety and quality food here, but no free soup base keeps me from coming back (I'm the kind of hot pot person who don't care for any of the premium soup). The time we came was quite busy, and when we first arrived, we kept seeing the servers bring other tables their pot while we waited for what seemed like eternity (yeah we were hungry).
There's an good selection of sauces, but I personally don't care for communal sauce counters (for hygiene reasons), but it's not a big deal. At times they could be slow at replenishing the sauces.
I was leaning towards 3 stars, but I thought this restaurant is technically a bit better than most others, so I'll give it 4 stars (I wish yelp had a 0-10 rating instead).
Quality: 8/10. Services: 6/10. Value: 6/10. Overall: 7/10 (Not an average).
