Tired Umami Burger when I was in LA so when u heard it opened up here in Vegas I had to try it.
Food was same taste as the one in LA so consistency was good.
The only thing that bothered me was the drinks were pretty expensive. I don't mind paying 6-8 on an alcoholic drink but it was $12.
I would come back however, I would just drink water or soda cuz the alcoholic drinks are too expensive.
It prolly was busy but the waiter was neither nice or rude. She was basically doing her job. Nothing really stood out on the customer service.
