I had a group of 6 on a weeknight. Not a lot of tables in there, but it wasn't crowded and we were able to push two together. The staff consisted of two people. One to wait on us and one to cook. The server was new - very friendly, but not all that in touch with the menu. She did her best though and suggested a few dishes that did please our group.
The food had a lot of potential. Most of us really liked our dishes, but there were a few misses too. I ordered the kimchi pancake. It could have been good, but it was pretty burnt on one side (they put that side down of course). The charred taste sort of overwhelmed it. My bulgogi bento box was good. Would order that again. The main miss for my group is that we had a couple dietary restrictions that were mixed up, resulting in a shellfish allergy being served shrimp. The chef came out to address whether the whole meal was compromised as a result determined that only the shrimp needed replaced. I'm not 100% sure the diner was altogether comfortable with this, but she rolled on.
Overall, there isn't a lot of ambiance or frills, but I think you can get a good meal here. I'd probably do takeout next time.
