My experience at jjanga was nothing memorable. First off, the server didn't bother to ask how we're doing until 35 minutes after he took our order, and when he did, I had to tell him we didn't receive any of our food, the restaurant was not busy at all, with only two other tables at the time. We waited 40+ minutes for our food order! No apology from the staff, they just pretended like nothing happened. I definitely think Goyemon and Yama sushi are far better AYCE sushi joints. The quality at jjanga is pretty horrible, the only think I enjoyed was the baked rolls, where the quality of the fish is mass by sweet and spicy sauces. If you're into nigiri and good quality fish, this is not the place for you.
