Discovering the MOJO!!

I am currently waiting for a phone call from some guy who I don't remember meeting. Here's what happened: I was working and an attorney that I know called and before I passed him on to the other attorney he said he had a personal question. He said he has a friend who is also an attorney that works out of a different county and he wanted to go out with me if I was single. That is a total ego booster right there. Well I found out a few more details about the guy...his name and he's supposedly very successful financially, but I still have no clue what he is like. I asked my ex if he knew him because apparently he's got some downtown Roanoke connection and the ex said he's a nice guy but I probably wouldn't be attracted to him...well? Anyway so now he's supposed to call me at work to set up a lunch date. I am very curious to meet him...again apparently (how terrifying are first dates?) Should I go, should I not? what's the advice?
