Howdy everybody, I don't usually post on reddit, but I needed some ideas.

My buds are coming to Houston in a couple weeks and so far we plan on going to Chinatown and maybe a museum or two. What else is good to visit while you have a few friends in town? I've been to only a handful of attractions here like the aquarium, the museum of funeral history, and an art gallery. There must be some hidden gems or key spots for reacquainted friends to explore. I don't just want to check out restaurants while I'm here.
