I'm looking for great-tasting, reasonably-priced Korean food catering for about 40-50 people or so. I have looked at a few catering companies, restaurants, and supermarkets, but I'm unsure of the quality of the food. Some seem to offer per-person rates, while others offer dishes a-la-carte. Which is more cost-effective and what are my best options? I would prefer to pickup the food in Orange County, but LA would also be acceptable if it's a better deal.
