Looks like these guys have some rentals. Good replies so far wrt eating, I might suggest a few in town places like threadgill's, chuy's, or z tejas. Out of town coopers in llano or opies in spicewood. Could also rent biciycles and ride around town lake which is an easy 10 miles. If you want to see hills and curves go west, things flatten out east of town.
New F1` track will open this w/e, might be worth driving by on our 85 mph roads.
