Came here for dinner on Sunday and the restaurant was busy. Jjanga has a lively atmosphere with K-Pop playing throughout the restaurant. The one thing I can say with total confidence - You will not find another sushi bar in Vegas with better service than Jjanga.
Every server that passes by your table asks if you need anything. Between each server passing by...there is a busboy who stops by to clear empty dishes or refills drinks. I was so amazed that I actually counted how many servers stopped by our table within a minutes timespan and I lost track.
The food is good. I found the sushi to be warmer than I would prefer. I don't think they cool down the rice enough. Their spicy tuna mix was pasty. I don't think it's freshly chopped per order. Nigiri fish to rice ratio was really good. Big pieces of fresh fish.
Definitely worth a visit!
