I live in Springfield, MO.
Not a bad college town at all. Someone suggested eat at Lambert's. Fucking do it, but it's not somewhere to go unless you're with a group of people.
Tonight is Tuesday...hmm
Ernie Bigg's Piano Bar is pretty cool on Tuesdays. No cover, live band karaoke. The musicians are extremely talented and there are lots of good singers there. $2 wells.
Pretty much any place you go to will be overrun with frat boys and various college kids. How old are you?
I might be able to suggest some better stuff..
edit: if you'll be here for a friday night look up "art walk" down town. It's always a lot of fun. You could check out a movie at the Gillioz. Surprisingly we have some of the higher rated Chinese food places in the country. I suggest Canton Inn. There's a rock wall climbing gym too that's pretty nice and cheap. I believe it's called Petra.
