The Cabana Grill is located poolside the MGM Grand Pool. If you choose to "dine in" they have an outdoor area that is separated specifically for restaurant patrons. This area has fans blowing and mist machines going to keep you cool in the intense heat.
There is also a self serve area where you can go up to a counter and order the same food and either take back to your room or eat in a shaded area with outdoor tables and benches.
I came here twice and participated in both options. The dining in experience was nice and relaxing. You are able to get a nice lunch while also taking in the poolside atmosphere. I had the club sandwich and it was huge! The fries were amaze balls as well. I was completely stuffed after this meal which rarely happens for me. Prices were relatively inexpensive. A cheap lunch could run you from $10-20. They do serve alcohol hear, as they do at almost every establishment in Vegas.
I also had the pizza from here to go and this was not as good. Though it is cheaper to grab your food on the go it is much more of a pleasant experience when you are seated and dining under the fans. The slice of pizza was just average and it was $8. For a dollar or so less I could have went to Bonanno's in the food court. The fries on the go option was nice though.
Cabana Grill is the only but a good poolside option.
