I'd say this is a good experience for those who've heard the legend of White Castle (much like how East Coasters need to try In N Out, us West Coasters need to try White Castle) and only have tasted the retail supermarket frozen freezer version of these mini silders.
I was actually fairly excited at the prospect of trying the White Castle Burger.
They sell them individually and they're over $1 each. If you look at the special "dollar menu" items at rival fast food chains like McDonald's, Burger King, Carl's Jr., Jack in the Box, Wendy's etc. and take a step back and analyze how much food you get in a White Castle Burger vs a full sized burger, it doesn't add up 'tho. It takes at least 4 White Castle Burgers to equal a standard burger (not even a Whopper or a Big Mac, Quarter Pounder, Jumbo Jack or Happy Star).
So, to that degree, I think the mini-burgers are worth at most $0.50 each and ideally, not to be thrifty sounding, but in analyzing pound for pound and bang for the buck comparisons to their peers, maybe 3 for $1 or 4 for $1, so about $0.25 each (they did debut after all for $0.05, a nickle each, albeit back in the 1920's nearly a century ago.
Beyond the pricing, the food was unique, it has a soft steamed bun with a pickle and chopped cooked onions with a very thin and sort of slimy (not in a bad way) square (a la Wendy's) beef patty which is reminiscent of those Banquet/Swanson's frozen dinner "Salisbury steak" or sliced meatloaf.
It's quite tasty and I like 'em where others may feel they're stoner late night snacks, I can see eating 'em and easily going through 4 and possibly eating 10 and maybe even being up to the challenge of over indulging to potentially eat 20... and those statements are both a testament to the fact they do taste good, but they're also not so filling and very small in size.
The french fries are really weak 'tho, previously frozen crinkle cut, very thin, small portions. I'd roll the money to be spent on fries towards other food purchases. Del Taco uses similar styled fries, but they're much better in pricing, portions and execution (fried nice and fluffy inside and crispy outside).
I rate this * * * three stars, "A OKAY" which means I'd recommend it and come back again, but it's not necessarily so unique that I'd crave it and put it on my "must go to" list whenever in the area, which is in part my criteria for my rankings of places that earn four or five stars.
This location is on the Vegas Strip in a very safe area, easy to park if you park in a hotel casino I'm sure, congested to get to by car via the Las Vegas main strip, but convenient if you're staying in a local hotel.
