Just had lunch here. It's a Monday and the place was practically empty. This was my first SS experience at this highly touted establishment. This one is located at Downtown Summerlin, a new high-end shopping complex.
I got the Shack Stack @ $7.95 (burger with a patty-sized cheese stuffed portobello mushroom) and fries. The burger/portobello was very tasty, however, rather small, especially for the price. The meat patty itself was pretty skimpy. The fries were like anywhere else...nothing notable.
I then had the mint chocolate frozen custard (since I wasn't full from the burger at all) which was pretty tasty also. $3.60 got a small scoop. Not cheap, but not outrageous.
This is a trendy millennial's hang. Kinda disappointed, but I'm not much into trendy.
Oh, service was good and attentive.
GOOD: Tasty burgers; good service.
BAD: Pricey; small portions.
MHO: Bachi Burger beats this place by a mile.
