Where can I meet an [actual] nice guy in Philly?

I am newly single and am ready to go out in the dating world again. Where can I go in the Philly and Philly suburb area to meet guys who are mature? NO FRAT BOY TYPES!!! I am 32 and would prefer someone in their 30's at least. Please don't say Rittenhouse Square, as it can be soo snobby in that area. I like professional men, but I also like a bit of 'laid backness'.. Please help.. I don't want to go through the same ridiculous relationship I just got out of!
