South Padre/Port Isabel Texas

Louie's Backyard on the gulf. Dirty Al's on the Laguna Madre
side of the Island. If you want to go into Mexico go in at Progresso. Stay within 3 or 4 blocks of the boarder bridge.
Very safe. Inexpensive food, drinks and med's.
Also, SpaceX is in Boca Chica. Check if anything is scheduled for launch while you are there. Nice isolated beach there.

I grew up out there. The sea turtle place is really cool. If you like catching trout and reds, hire a guide to take you out in the bay. Incredible fishing. The dolphin watch is fun too.

You also have a Dairy Queen and Whataburger on the main drag if you need something quick for the kids


Louie’s and amberjacks for live music


You can buy fresh seafood around the docks, but not sure there’s an actual market. You can get local caught shrimp/fish at the HEB in PI

Check if there are any shows in McAllen which is about an hour away.
