Going from east to west
Bermuda's on SPI
The original Wind Jammer in Port Mansfield.
The old Ft. Brown in Brownsville.
The old filling station near Oklahoma Rd in Olmito, they has some killer off the hook BBQ and Tacos. It was originally a stage stop on the Brownsville to Alice route, and it had the largest beer can collection in the Valley that I ever saw.
Savage's Fruit Stands, in Raymondville and on the 83/100 intersection in or near Rangerville, great BBQ and good fruit stuff.
Richards Sun Valley Inn in Harlingen, best gringo breakfast south of San Antonio.
Can't remember the name of the place, but a really cool little diner in La Feria.
Only open for a few years, but the Lost Trawler in Weslaco was really good, a virtual copy of the King's Inn. Supposedly opened by a long time employee of the KI, that came home to care for aging parents.
That Cajun restruant/beer joint in Donna.
Lackey's bird farm in PSJA, one of those cities. Neat place back in the day, like going to a bird zoo.
Kean's Deli in McAllen.
The old beer shop/ice house across from the big bank in McAllen. I think it was originally called the Ice House, then Pop-a-Top and then maybe something else. But the original one had really good cold cheap beer.
The original Johnny's Mexican food and cheap ugly jewelry shop in South McAllen. Great variation of Tex-Mex food, ala carte.
Las Cazuelas in Edinburg. Maybe it is still open, just south of the Bert Ogden dealership.
Butch's BBQ between Palmview and La Joya. Best BBQ in the Valley IMO.
