Unfortunately gonna be the last time I come here. I've been coming to this place for over a year now and I order the same thing mostly, golden tiger and golden California roll. This time around I could barely even eat it. The sushi literally kept falling apart when I tried grabbing it. I'll have the pictures posted but this was very disappointing guys. I dunno what happened but between this visit and taking my lady there for our date night after work. I feel like you guys have gone down hill a bit. (Date night the waiter gave me the wrong roll and kept trying to say it was a golden tiger. I sat there like bro I've been coming here for ever, this is no golden tiger)
The food there was awesome! Tried the all you can eat for the first time. It eas amazing!! Food came in nice, hot and warm. Definitely come here more! Food : 5/5 | Service : 5/5 | Atmosphere : 5/5 … More
While everything tasted pretty good. This was the only thing I ate today. Not sure what caused me to throw up and soil myself. Maybe it was the quail egg shooters or green mussels that I didn't get a chance to take a picture of. Dine in: Yes Takeout: No … More
