I work in construction, so I'm not originally from Weslaco, but I was pleasantly surprised that the food was hot. It was good and tasty. I ordered it online, and from where I was working, it's about a 15-minute drive to get there with traffic, so I wasn't really expecting the burger to be hot because usually, when you order on an app and go pick it up, the food isn't always hot. So, being that I had a bad experience in my hometown with Sonic, I wasn't...

March 2025

Stopped in for ice cream and was disappointed...I ordered the Turtle Truffle Nut. They Sprinkled some stuff over the top, but nothing down in the cup! I guess I'm too used to a Blizard that has whatever flavor you order all through the ice cream instead of just on top. But the ice cream part was good!

March 2025

I feel like compared to the Mercedes and Elsa Sonic locations, the Weslaco one is kind of lacking. I went by a week ago to order a queso wrap, and it was not up to par compared to the other locations; the chicken was dry and the wrap and cheese were cold. However, the service was really good, and overall, the location looked clean and well maintained. I’ll probably go back soon to try the mozzarella sticks.
