Sweet. I'll be there at tip off Major.
Haven, let me know where you are coming from. I can give you fairly precise directions. However, it's at the Northwest(more like just north) corner of the Barton Springs Rd and Riverside intersection. The address is 306 Barton Springs Rd. Aussies has a low roof and sand volleyball courts in the back of it. It's got a fairly small parking lot. If you need any more info just ask.
edit: Low roof is more like one story(I'm having trouble remembering the outside.)
You can go to www.austin360.com
and click on one of the resturant links. From there you can type in Aussies. Once you've done that, they'll provide a map. There is only one in town so it should be no problem.
