A new Korean-Japanese style BBQ house called 'Yakiniku Gen' has opened in Midtown East, on 52nd Street between Third Ave. & Second Ave. (next to Hidechan Ramen) a couple months ago.
I have been there twice for dinner and twice for lunch so far, and its lunch specials are quite good quality for the price. A couple notches better than Gyu-kaku for similar (if not the same) price ranges.
For $20, I got special kalbi & harami, accompanied with rice, very tasty akadashi miso shiru, three side dishes, Korean seaweed, and salad.
Meat quality was very good for the price. (attached photos)
