Ozona's was an AWESOME spot for our rehearsal dinner! We were in one of the back rooms (The Garage Room) with about 50 people and it was the perfect amount of space. They were super easy to work with and the food was great (like it always is).
Another plus is that you have the room from about 4pm until late (close I think - we left at about 10pm-ish to get ready for the wedding the next day). They had a place to hook a computer for a slideshow on two large tv's and had two servers that took care of our party.
Service was great, food was great, all of the managers are super easy to work with. I would definitely recommend for a rehearsal dinner or really any kind of party. They have some bigger rooms as well, but the Garage was the perfect size for 50 or so.
