I really appreciated how Kaleema was taking care of a dozen people at once, with what looked like a backed up line; but because she was handling things so efficiently, I had my order hot and paid for in just minutes. They say good people are hard to find - Kaleema was a joy to find on a hungry night!

Great service the pizza was really good. I will rate this place a 7/10. They have Parmesan there if you'd like it too.

I go to the casino once a week and always have Zizi pizza. It is really good pizza! What makes it really nice is Kim! She always greets you with a hello and smile. Kim makes you feel good! You have one good employee with Kim, and darn good pizza!

Zizi's Pizza is definitely one of the more affordable places to eat at MGM National Harbor, with slices averaging to about $5 each (though a whole pie can quickly get up to the $30-$40 range). It's basically a Sbarro with ready-made pizza slices on display, waiting to be reheated and brought back to life. We came around 9pm after a concert, and pickings were already slim. They were out of calzones, out of mushroom, out of veggie, and out of cheese slices; a new pepperoni pie was in the oven. I asked if they would have other pies available, but they said what was on display was all they had. Normally, 9pm at a fast casual joint - ok, close to the end of night, I understand why stock is low. But, given that this is a casino environment (casinos never sleep) and they're actually open until 1am, they should have more fresh pies available or in the works. Only the carne and bbq chicken pizza were in stock, plus a stromboli. The carne pizza looked like it had been sitting out too long, with cold cheese congealed over... so I opted for the bbq chicken pizza. My slice was heated up and packed in the standard to-go box. We also asked for a cup of water and the worker thoughtfully filled cups of water for everyone in our party. With the food court atmosphere, it's safe to assume most people will dine in. The employee ringing us up didn't make any assumptions and offered to bag the food up to-go. He also made sure to provide utensils and a side of marinara sauce for the Stromboli. Kudos to the employee for doing a thorough job. The bbq chicken pizza slice was average. There was plenty of chicken and you could taste the cheesy goodness in each bite. The crust could've been a little thicker for my tastes, but it was adequate to hold up to all of the bbq chicken toppings. All in all, ZiZi's is a solid option for a quick and cheap dinner at MGM National Harbor.

Probably 3.5 stars, but I'll round up. Not a bad option if you're craving pizza at the casino. Try to get a slice from a freshly cooked pizza, as some of the pizzas on display looked like they've been there for a while. The 2 slices filled me up. Very cheesy and the crust was nice and firm. I'll return no problem.
