We stopped by on an early Sunday afternoon for a snack. I initially thought it was a regular-sized donut place. But mini donuts are good too.
The location is convenient if you parked in MGM's garage, but I parked at the free parking at the Tropicana so it's a bit of a walk over to this underground hallway at the Grand.
It's only a counter, but it's a nice counter. The service is friendly.
Basically, delicious mini donuts in a variety of flavors. I won't necessarily go out of my way to get these, but if you are in the area they are worth a taste.
