Houston solo trip recommendations

Hi everyone!

I am 32 (F) and am thinking about relocating to either Dallas or Houston. Other than visiting the temples there, I haven’t fully experienced either city. I was thinking about visiting for a week (few days in Dallas, few days in Houston) to get a feel for each city and which one I’d enjoy living in. I work in healthcare and here are some things I’m looking for:

-diverse with lots of vegetarian friendly food options (I’m a huge foodie) -large airport (I like to travel) -city feel -safe -things to do (dance classes, farmers markets, concerts, etc)

That being said, what recommendations do you have for me to visit/see during my 3-4 days I’ll spend in Houston?

TIA!
