Cantina El Tesoro is on a side street on the south side of Decatur. It's in an old house on a leafy street. It's a great setting, particularly this time of year. They even have a kids play area---not every bar has that.
I tried a taco and a tamale for lunch. (I didn't plan to come here on Cinco de Mayo, but it was a nice bonus.) I definitely prefered this place to Verde The taco was brisket and the sauce added a little punch. The tamale was a big hit. I had a green pork tamale. The sauce gave just enough heat to make a point without masking the other flavors. The pork was succulent and the corn meal was very corny.
