I've had two recent meals at Han Il Kwan, which is in the Richmond District on Balboa. First meal was with a party of 10, second time was a party of 6.
Overall, I like this place.
Service on both visits was friendly enough, but the place seems slightly understaffed and it's hard to get anyone's attention if you need something. The restaurant takes reservations, which is a big plus for a large group. The restaurant is kind of cold and can get smoky from the self-service BBQ, but there are plenty of tables (both round and rectangle) for large groups.
Food is good. Panchan are plentiful, and there's also always a complimentary dish of some type (either tofu stew or fish). On one visit, we ordered from a set menu, which comes out to about $20 per person, and includes two types of meat (self-bbq or already cooked), tofu stew, bi bim bop, sauteed squid, japchae, some fried things, and egg custard. Tons of food for the price, and worth it if you like those items. On the other visit, ordered a la carte, and price was basically the same, since we didn't need the unnecessary squid or fried dishes. BBQ meats are good, both cooked ourselves and when they came already-cooked. On both visits I had the beef ribs and the spicy pork. Not necessarily any better than places like Brothers, but big portions and tender meat. It's served w/ bean paste and lettuce for wrapping.
Parking in the area is really difficult.
