Koja unfortunately was just okay. They have this purple rice, so our friend wanted to try it. I got a bulgogi be to box. The meat and veggies were tasty. The meat reminded me of ground beef (in a bad way) but the flavor was fantastic. It comes with the purple rice (which was dry) and it had a deeper flavor than most rice which was pleasant. The glass noodles were a little funky tasting but had a normal texture. The sushi served was stuffed with tempura fried sweet potato and the texture was less than pleasant as the fried sweet potato quickly became salty. I have to be honest though, for $10 you can't expect much else for this much Japanese food. I had a large hot sake and it was pleasant. Not a terrible place but certainly not amazing. It should be noted that the fish filled sushi was tasty and reliable.
