Whenever I go to Korea, my go to food is curry katsu. Unfortunately, most places I've come across don't have it. Not only does Tokyo Grill have it, it's amazing. Their curry is more sweet than spicy and has a lovely aroma. Their donkatsu is nicely fried and fits perfectly with the curry.
Price is reasonable at around $12-13 and the dinner portions are quite filling. I haven't tried anything else there even after going 4-5 times because I can't resist going back to the curry katsu.
Only downside I'd say is that they only take cash so I have to make sure I visit a bank before going. Also, while I haven't had an issue yet, the place is quite small so definitely not a place you can take a large group and expect to have seats for everyone.
