This place was a nice surprise. Seriously, Harrah's has pulled off a coup grabbing this place.
The comic book Soviet decor was pretty neat. The relaxed atmosphere and knowledgeable wait staff were a definite plus.
I ordered the backyard BBQ burger and my wife ordered the American. Both were cooked as desired. We were impressed. In addition the waiter talked me into the Captain Crunch milkshake. That was a good move. In hindsight, it would be nice if the diameter of the straw they served the milkshake was a little bigger. I found the nuggets getting stuck in the straw and I had to nearly suck my brains out to clear it.
Overall, I look forward to going back to KGB. If you are looking to get your burger on in LV for a reasonable price, this is the spot. The location on the strip is pretty central and it isn't hard to find this place inside Harrah's.
