If the “19” in your name indicates class of 19, ignore the old dudes on here.
Drink Friday/Saturday night off W 7th (East of University, South of and along 7th, North of Lancaster, West of and along Foch). Tons of bars. Plenty with TVs to catch others gsmes. This is the area most TCU students go out. If you like burgers, Rodeo Goat in there is awesome. Downtown has some good bars. It’s an older/less educated (read: Denton) crowd. If you have time to blow it’s fine to visit - when I was a student we went out downtown before W 7th built up. Demo has changed since. Downtown is awesome but ignore you’re an undergrad it’s probably not your night scene. You might check the Billy Bob’s concert calendar for Saturday night. Otherwise the stockyards blow with olds and tourists.
If you want a bite by campus - Dutch’s on university or Fuzzy’s tacos (the original) on Berry.
Uber is easy - no need to rent a car most likely. Designated pick up on Cantey St on TCU’s campus.
Best BBQ is on Magnolia - Heim. Everything is good. Order a side of bacon burnt ends.
If you’re doing breakfast Sunday - early or late - ol south is the greasy spoon type place and torchys tacos is a regional chain that has great breakfast tacos and a full bar. There are plenty of true brunch places too if that’s your thing.
If you want to drink local - TX Whiskey and TX Bourbon; Rahr, Martin House and Wild Acre beer.
Protip - stay out of dallas.
