Houston is one of the most diverse cities in the U.S., and its  11,000-plus restaurants across 70 cuisines are the proof. A standout: Viet-Cajun food, an only-in-Houston mashup that will have you asking for seconds. When you’ve had your fill, head out to explore the city’s arts scene, with opera, ballet, symphony, and 19 museums at your fingertips. And if you prefer a trip to the stars, the Johnson Space Center will get you there.
