Burger Libre is the burger place. Russell Ybarra owns
I had thought I had heard from someone that he owned Floyd's but as you point out, turns out I am wrong about that..
Back when Floyd Landry had Floyds in the Montrose in the 90's, I used to eat there. Due to some past problems he could not get a liquor license. But if you asked, he would give you a Dixie Beer, just one. Said the food needed it.
I had been trying any restaurant with "Floyd" in the name in the hopes of finding him again since. The Sugar Land one was where I first found this version of his cooking.
