The Japanese here is good, the Korean is better. (Prob because it is Korean owned) I usually like to pop in here quickly for a bite and watch a game on the flat-screens.
After discovering the Hwe Dup Bap here (mixed Korean sushi rice) I don't get anything else. It's a bit pricey at $16 but the value is there with a ton of fish mixed with rice, veggies, and chogochujang (Red Pepper Paste w/ Vinegar). It doesn't look pretty but it sure is a tasty bowl of goodness.
The Japanese side of the menu is decent but I found it not as strong in comparison to the Korean offerings. Sushi is average for the price though the nigiri slices here are quite phat. I couldn't put my finger on it but the sushi rice here falls flat compared to other places and the nigiri comes sans wasabi. Gyoza here is cooked perfectly and worth a try in its perfectly fried glory. Tempura didn't fare as well as the veggies were heavily breaded taking away from the shrimp.
It's pricey but the location and quality Korean keeps me coming back. (7 visits and counting!) Love the ambiance and music.
All in all, Gangnam is a great addition to the other Korean places near campus like Paradise Hawaiian and Grilled Ave.
