Came here on a Saturday evening without reservations (for 8 people) and they were able to accommodate us. It started filling up really quick so we were glad to find a table and not have to wait. However, the tables we were seated at were really small and we had a hard time organizing the dishes just so we could fit the rest of our orders. There's also not much ventilation in the restaurant and it doesn't help that it's grill-your-own so if you plan on going there on one of these hotter days (like we did) prepare to sweat or step out every now and then because I'm not kidding about how hot it is in there.
The service was good - she came pretty often to make sure our waters were filled and it wasn't too hard to wave down a server when we wanted to order more. The food was great. I loved the meat - especially the beef. The bachan was also really good - a lot more better sides than most korean spots I've been to. One thing I could probably say besides the heat, is that the portions of the meat could be bigger (just in my opinion). Otherwise, it was still a good experience and a great way to end your night with friends.
