HEB is a grocery store and obviously an acronym. It stands for "Here Everything's Better." Honestly, I'm not sure if everything really is better at HEB, but it's a pretty great place to buy things to put into your stomach. It has decent prices and food that tastes great and won't give you salmonella.
Texans love HEB dearly. The point behind the fanaticism is that it's ours.
The point being that if I had left HEB off of this list, a few Texans would read it and be angry that it didn't make an appearance. HEB is a beloved institution. The fact that people buy their bread here doesn't make it any less special. The fact that everyone buys their bread here does.
