We'll get to the pizza in a minute, but the star of this show was the Mozzarella Bar "cheese board" appetizer. You can choose from a selection of meats and cheeses which are served to you on a wooden cutting board. Served with flat-bread from the wood-fired oven, olives, house pickles, mustard, fruit, and nuts.
We ordered the Humboldt Fog Goat Cheese, Burrata, and Prosciutto. I would seriously go back to Five50 just to sample more of these meats and cheeses. Really good.

The pizza was good as well, but I didn't like it as much as my wife did. I thought it was pretty comparable to most other wood-fired pizza I've experienced. You can choose from a menu of pre-made concoctions, or build your own toppings. We built our own with mushrooms, olives, and tomatoes if I remember correctly.

Five50 also offers a take-out counter, which is very convenient considering its location near the poker room and sportsbook.
Overall Five50 is a great casual option at Aria, especially considering most of the other dining options on property are on the upper end of the pricing scale.
