Things to do in Houston for Summer

I’ll (22m) be in Houston this summer for an internship before my last sem at University (2 days in person, 3 days remote work) and will probably have some leisure time to roam around. My work is in the center of downtown-downtown. What are some cool things to do in Houston? Cool places to eat, do work, or study? Are there places to avoid? i used to go to houston a lot when i was younger but that was a long time ago. Any Tips, advices, etc. is appreciated. – i’m into thrifting/vintage clothes – eating (i’ve been to the bellaire area a lot bc of family friends and am big on Asian food) – working out
