I'm not gonna lie: Finding good eats around Intercontinental Airport (or, if you must, Bush Intercontinental Airport -- true Houstonians still say "the Summit," "Transco Tower" and "Intercontinental Airport") is tough. This isn't like eating around Hobby Airport, where you're smack in the middle of the city and interesting dining neighborhoods like South Houston abound.
No. Greenspoint and the surrounding areas near Intercontinental are mostly a wasteland of chain restaurants, mediocre hotels filled with exhausted business travelers and one of the city's saddest malls.
That said, it is still possible to eke out some good food in the area. This is Houston, after all. If you can't find at least 10 decent restaurants within 10-mile radius, you're not trying hard enough.
Even more promising is the fact that many of those good, decent restaurants serve some of the city's most iconic cuisines -- Tex-Mex, seafood, Vietnamese, Cajun and Southern -- so you can direct those sad-sack business travelers to experience a little of Houston while they're in the area. I know from experience: Room service gets real old after a few trips.
