It is the nation’s fourth most populated city. Diverse residential neighborhoods and areas of restaurants and shops extend far and wide. The Museum District is the city’s cultural center; Upper Kirby and River Oaks have upscale shopping and dining; Montrose has cute bungalows, original shops and eateries; Washington Ave is nightlife central and the Heights has historic homes and boutiques. Two of the town’s main attractions – NASA’s Space Center Houston and Galveston Island – are not far, but outside the city limits.
