I live in San Antonio and have not found a better burger in San Antonio than I ate at Sammy's. It was simple, but flavorful, juicy, and delicious. Exactly what you'd expect from a cheeseburger. I've also had the enchiladas there and they were good too. I'm from a small town similary to Castroville and this restaurant makes me feel at home. It's very simple so don't expect a 4 star experience. Just simple comfort food.
Pros: Good Food with a down home feel
Cons: could use a renovation
