Since folks are getting nostalgic about Jaimie's, I thought I'd make a comment about Tres Amigos at the intersection of 183 and 290. My bf and I have been twice over the past week.
We both used to go there as kids with our families and I will also add that my Grandmother made tamales there after her 25 year stint at the Green and White Grocery store. Neither of us had been there for a while so we decided to check it out.
The puffy tacos I remembered as a child did not disappoint. They were stuffed full of spicey ground beef, fresh iceburg/tomato and shredded cheese. My order came with 2 tacos and I could only finish one.
The bf had the Nuevo Leon plate on both trips. I had the Guadalajara plate on the 2nd trip. We both enjoyed our meals and decided this was our new (old) go to place for Tex-Mex. The prices are good, the staff is very friendly and the restaurant is clean and inviting. You have a choice of sitting at a booth in front of the bar or sitting in dining room. It wasn't crowded on either visit. There was a steady crowd but no wait. The prices are very reasonable.
If you like old school, austin owned places with good food and prices, try Tres Amigos. Hopefully you'll enjoy it as much as we did.
