Downtown suggestions??

Hi! I’ve lived here all my life but haven’t really spent any time downtown. I’m trying to plan a full day of stuff to do/see and was wondering if anyone has any suggestions for things less known or places that are fun and worth it.

We’re going to start the day at Day 6 coffee co. And walk from there. We want some shopping, grab some lunch/drinks, see some sights, art, maybe listen to some music?? Idk… just trying to romanticize Houston as much as one can 💀 we’re also planning on going to The Cistern later in the evening.

Anything thats not super popular (or expensive) because I do know of most spots or maybe something that is popular but it’s definitely worth it!! I appreciate it!!!
