If you have of a party of more than four, its always a good idea to call ahead. Best case, they tell you they aren't on a wait and you should be able to walk right in. Worst case, you cut your wait time by ten or so. For parties of four or less, its only really necessary to call ahead during peak business hours. Also in addition to calling, you can always use the no wait app from the android marketplace.
They do. If it's peak time with mall traffic than even for two I've called just before leaving. Than my wait might be 5 instead of 15
You can just come in unless you have a huge group. Most seating accommodates 3-5. If you need a lot more than that, I'd call!
No, unless you have a party of like 10+ they don't take reservations. That's the policy of Chili's nationwide.
