Sadly, the restaurant options near the airport are somewhat lacking. There are a few of the Pappas restaurants (Pappas BBQ, Pappas Seafood, Pappasito's Mexican) nearby in the Deerbrook Mall vicinity. There's Saltgrass Steakhouse (Texas [Landry's] steak chain). They're not bad. Everything else is at least 30 minutes away going toward downtown or the Galleria.
