They open at 11 30 or so, i dont think so.

Hey Rebecca, For large parties, we only take reservations ahead of time if you are reserving one of our private rooms in advance. Otherwise, we seat on a first come, first serve basis. If you can please call about 45 minutes ahead of arrival to give our managers a heads up regarding your party and if we are already on a wait, you can be added to the list remotely. Hope to see you in soon!

No. You have to go to New Braunfels. No Buckees in San Antonio that I'm aware of.
