Za's is good food for about the right price I'd say. That's really all you can ever ask from a restaurant. They got an incredible renovation after the fire - the upstairs rooms are now larger and filled with massive HDTVs playing music videos and the entire restaurant is now super clean which is a bonus for sure.
My go to is the Mac & Cheese with Buffalo Chicken. It's incredibly filling for sure, you definitely get your money's worth with this order and the flavor is superb. I admit I find myself wishing for a bit more buffalo chicken but I love the flavors so much it's still my go-to order. It also comes with some garlic bread which is good for mopping up the leftover cheese sauce. I've also had their sandwiches and pizzas (the BBQ chicken's pretty good) and been satisfied with whatever choice I make.
The customizable options on the food are good because you end up getting what you want, but they can seem to nickle and dime you. Pick you entree and then add a meat for a few bucks, add a sauce for another buck, add a drink for a few bucks, add etc for a buck....just something to be aware of when making your meal.
Solid 4 star restaurant though.
