With more info here's some more detailed information:
There's a really cool book store in South College Station (
https://hyperbolebookstore.com/about-us) and if she likes to read I'd take her to at least one of the local coffee places, particularly Polite Coffee in the Kyle House near downtown Bryan. (
https://politecoffee.com/pages/the-kyle-house) - During the school year it's always packed with students reading/studying/just hanging out. Polite is a roastery as well as a coffee shop so grab you a bag of beans to take home (I love their coffee, we have a subscription.) This is going to sound like a dumb idea but if she really likes reading, the College Station library is really nice and/or the Evans library could be cool to check out. Those could be cool stops if she's like some teens/pre-teens these days that are back into actual physical books as opposed to Kindles.
I would check out the directory of
Century Square first and see if there's some places that are up y'alls alley before committing there. I'd say there's two "walk/eat/shop" areas here, Century Square and Downtown Bryan. Century Square is definitely more modern, high end shops, etc. Downtown Bryan is a little more classic Texas downtown but they've done a great job with it over the last couple of decades. Lots of interesting shops and stuff. It's too bad it's not next week for First Friday where there's street vendors and performances and that sort of thing.
We have a TON of breakfast/brunch options, but stick with the local ones for a first visit.
Stella Southern Cafe (near Hwy 6 and Rock Prairie), the students love
Mess Waffles (Century Square),
Wild Grain Cafe is relatively new and I haven't been but everyone says it's great (Texas Ave. towards Bryan.) There's even more that I'm sure people would recommend. I love Jesse's Tacos (And La Familia in South College Station) but I'd think a middle schooler would prefer a nicer place.
I would actually recommend against Aggie Alley for the regional, it's going to be packed and absolutely nuts out there, standing only, and it'll be hot. My recommendation would be to find some GA tickets and sit in the grass in right field. If we win the Friday afternoon game though the Saturday game doesn't start until 8 so that's going to be a pretty wild and rowdy scene at Olsen. The kind of environment where's she's either going to fall in love with this place or completely write it off as a possibility. High risk/high reward environment there.
This isn't local to College Station either because there's a few of them around the state now, but we have a
PopStroke putt putt golf place which is a really fun way to just hang out (also at Century Square) depending on your schedule.
