The Burger Guys 12225 Westheimer. It's a pretty good drive down Westheimer but they have great burgers. They also have some kind of LSU connection because every time I've been in there at least one of the cooks has had an LSU cap on.
Pappa Bros for steakhouse. Masraff's for high end seafood. Zabak's for lunch, India's has a great lunch buffet, Argentina Cafe, Chama Gaucha is a Fogo/Texas de Brazil type place that gets pretty good reviews, RDG Bar Annie or Phillipe if you like rampant douchbaggery with decent grub.
