I shit you not... but really just pick anything with 20+ reviews and follow the ranking (of course check the menu to see if there's anything interest you).
The number 1 for example (Sam Oh Jung) is feel-good home style korean food. I always go for one of the hotpots (the one with beef/octopus is great or the beef/mushroom one if octopus isn't your thing). They always give 6-8 banchans and are quite good. And the steam pork belly with cabbage/radish is must try IMO.
I liked the BBQ and fried chicken from Todamgol if K-fried chicken is your thing.
Sahm Gook Jih Palace is the K-Chinese food I was talking about... it's a hole in the wall kinda place. But nothing not to like. Great flavour, great portion and good price.
They are all fairly close by... but if you are in a hurry, you can always just hit H-Mart and the food court isn't bad either. I got a korean style tonkatsu because my kid wanted the other day and GOD it was huge. All this for U$10... actually bothered to take a picture because I was genuinely surprised of how big was that thing
