I don't like Torchy's but their guac/queso combo thing is solid. I don' really **** with queso often, dairy doesn't love me.
Good question for @Blake I don't remember their queso, but man that was a top-3 hungover breakfast spot when I lived in that area.
A friend brought HEB's Brisket Queso over for the superbowl, it was surprisingly good. It's very easy to make, just put in the oven at 400 for 10 minutes after adding half a beer. https://www.heb.com/product-detail/h-e-b-meal-simple-tex-mex-queso-with-brisket/4524083
I make a queso on the grill in a cast iron skillet using seasoned taco meat, habaneros, jalapenos, tomatoes and onions...I'm proud of it I love queso.
I prefer guac but I never order it at restaurants. Like a fart I prefer my own brand. Trudy’s in Austin puts a fat dollop of guac at the bottom of their queso and it’s pretty awesome.
When I moved into the slack shack years ago and realized all I had indoors was a toaster oven and hotplate, I totally got with the cowboy-style ethos of cooking in cast iron over coals. I've reverted to civilization since then, but I still use those same lessons.
This is a.classic 'why not both' scenario -- guac and queso is an all time classic, but if I had to choose one I'd have to go with guacamole.
