This Olive Garden does not take reservations on weekends. However, you can call up to 30 minutes before your scheduled time of arrival to save your place in line and let them prepare for your party. We did this for a large family group on December 1st and it worked very well.
It's a good idea to make reservations for any evening. It'll cut down on your wait time substantially.
I'd say it's always better to reserve at any olive garden just to be safe.
Depends on the size of your party.
