Went to Kang Suh last night, and two friends and I shared the kalbi and spicy pork barbecues, and a spicy beef/vegetable soup.
The barbecues were terrific, but to me not noticeably better than, say, Woo Chon. The soup was good, if not distinctive. And as others have noted, the panchan is mediocre at best.
The service was, well, weird. On the one hand, everyone was extremely friendly. When we arrived, the restaurant was near-full, but became progressively less busy as the night wore on. Yet we were rushed during the meal. Every time a server came to our table, near-empty plates were cleared without consultation, every last square inch of the grill was filled by meat on the plate.
If this were merely a tactic to turn tables, I would understand, even if I wasn't happy about it. But once we were finished, there was no attempt to hustle us out -- in fact, we lingered quite a while and the servers seemed to be in no rush to pick up the check.
Other tables were also full of post-meal loungers.
Is this a cultural difference that I'm not aware of? We would have enjoyed our meal so much more if we had a little more control of the timing of our meal. I've been in Korean restaurants, especially during busy lunch hours, where I've been rushed, but couldn't quite figure out what was going on last night at Kang Suh.
