This restaurant has no right to name itself "umami" at all. Please change the name asap. I have dined a few times at LAX location of the same chain restaurant and found their burgers some what "interesting" and don't mind to try them everyone going through LAX. However, the one here in Las Vegas was terrible. Taste is bad, service is bad, and ........ Raw meat in bans are served and don't have any taste to it but just weird feeling to my teeth. I stop eating and waiting for any server to come by. ........ Well, no one come by for another 10 minutes so I decide to leave because I needed to go you know where....... I came back to pay for it but.......
