I know that Willowbrook Lanes has a Friday night men's league. My dad and best friend bowl in it this year. Broadview Bowl also has a solid Friday night league. I believe it's called Lane 1 Friday night men's, or something like that. A bunch of guys I used to bowl with are out there.
If you are in Joliet, you may also want to look at the following centers:
Orland Bowl
Thunder Bowl (Just off LaGrange Rd. (Rt. 45) by I-80.
Pioneer Lanes (Located off Rt. 30 in Plainfield; an old friend of mine owns it)
Centennial Lanes (Tinley Park)
Strike & Spare I & II (One is in Lockport, the other is in New Lenox or something like that)
Brunswick Zone Woodridge (Located on 75th St. just south of I-355)
Brunswick Zone (there's a new one just off I-55 on Weber Rd.; I'm not sure what they're calling it, but it looks huge).
I'm not sure what any of these places offer on Friday nights, but all of the centers are close in proximity to you, so it's at least worth making a phone call. I hope the list helps.

I've only bowled 300, but I've benched 345
