Burger Bar, located at Mandalay Bay, had the highest quality meat in a burger than any place I've tried. My friend told me about this place and its Kobe beef burger, but I had no idea how good it would be.
Food:
1) Kobe Beef Burger - Kobe beef was really juicy, tender, and every ingredient was fresh. Definitely worth around $20.
2) Sweet potato Fries - it's a must with the burger.
Service:
The staff were on top of getting people seated, served, and were efficient. However, there was a long line, so we had to wait about 45 minutes. I suggest you go early to beat the rush, or you'll wait awhile.
After losing a good amount of money, Burger Bar cheered me up as I left Vegas on a Sunday.
I'm extremely picky about the places I'll return to and Burger Bar is definitely a place I try to visit everytime I'm in Vegas.
