Wolfgang Puck is inside the MGM directly across from the KA show entrance. The restaurant is open and looks more like a casino cafe than a traditional restaurant style enclosure. It's rather small, but has a large glass party room. Small bar!
If you're ok with spicy, get the grilled shrimp appetizer! The shrimp are huge, the polenta pairs perfectly and the spicy red pepper sauce gives it the perfect kick.
The Halibut was good, but nothing special. I wasn't very impressed with the dessert menu (we ended up going to New York New York for a shake from Shake Shack, haha)
I haven't been to the other Wolfgang Puck restaurants in Vegas yet, but I will be after my positive experience here!
