This is for all the non-Koreans out there who've been/ or plan to try this place and need some quick facts.
Royal Boonsik is good. Yes it is a Korean restaurant but it is NOT your typical traditional Korean restaurant with like 10 different banchan and various soup and rice meals. You can think of it as a Korean style fast food joint with the traditional Korean boonsik favourites (in Korean "boonsik" means flour based food). So it is a type of Korean food very popular in korea, and it's not the healthiest stuff (BUT SO GOOD) so can be thought of as Korean fast food. So if you want specialty kimbap, deep fried seaweed laver rolls, deep fried squid and veggies this is where you go because your not going to get that anywhere else in k-town.
If you want to eat gamjatang at this place, by all means go ahead but just keep in mind that you are missing out on some of the other dishes!
I usually get the tuna kimbap, "kimmalee" (deep fried seaweed laver rolls), and "rabbokki" (Instant noodles and rice cakes cooked in hot pepper paste sauce) and dip the kimbap rolls and kimmalee in the sauce.
