There are many activities that should not be performed on an empty stomach, including swimming, surgery, and swimming 30 minutes after having your appendix removed. Acquire activity fuel with today's Groupon: for $15, you get $30 worth of Tex-Mex cuisine and soft drinks at The Oasis.

An appetizingly large on-the-water dining spot, The Oasis offers diners a lovely view from high above Lake Travis while they choose Texified Mexican cuisine from the dinner and lunch menus. Appetizers such as the Fireballs—spicy chicken bites invented by Sam Houston to commemorate his invention of Texas—ready unspiced tongues for a flavor onslaught ($9.95), and the blackened tilapia hidden inside the fish tacos make seafood believers out of fish-meat skeptics ($8.95 for lunch, $14.95 for dinner). Enchiladas come in pulled chicken, spicy chile beef, and cheese varieties, satisfying meativores and cheesivores alike ($8.95 for lunch, $12.95 for dinner).

The Oasis is supreme in its during-dinner viewscape, and early evening eaters can expect breathtaking sunsets set against a speech-stealing panorama. Head to the Tex-Mex sanctuary for inevitably romantic dinners or a calm, cliffside Sunday brunch before a long day of Dr. Quinn, Medicine Woman reruns.

Reviews

Although Yelpers are polarized concerning the food, all reviewers agree the views from The Oasis on Lake Travis are amazing, and TripAdvisors offer it a 3.5-owl-eye average:

• I am from Annapolis, MD so eating a nice dinner on the water and watching the sunset is something I expect to do at home. I was amazed at how beatuiful and fun Oasis was. – Estrick23, TripAdvisor
• Husband and I went here last Sept. with my cousin. The atmosphere was outstanding. The view of the lake and the setting sun was beautiful. Food was good, too. – SueB1018, TripAdvisor
