You want to call a few days ahead
Call them !
They don't have private rooms. There best they can do is set aside an area. Olive garden sometimes does reservations but sometimes they don't. Your best bet, as everyone else said, is to call them directly if that is the restaurant you are decided on.
You need to check with the restaurant .you want to go to personally
Cathy, the Olive Garden can get really busy and as someone who has big family dinners I really urge you to call and let them know when you will be there. That way they will be able to set aside an area for your party. Even if they don't take "reservations" in the normal sense they will able to set you all together. Which is really the same as a reservation.
Call them up i kown that they do reservation.
Not all olive gardens do reservations. If I were you I'd call just to ask when to make them, and if you can.
