POST Houston reinvents the former Barbara Jordan Post Office as a downtown hub for food, art, events, and skyline views. Monumental staircases rise through the cavernous building to Skylawn, a five-acre rooftop park, while the food hall below gathers vendors from many cuisines. Come hungry, explore the architecture, and time the roof for sunset when the city becomes part of the experience. That final detail gives POST Houston real staying power.
