Familar.....
....did it.
Worth the time / effort if you do not pay. If nothing else, it dinner and good conversation with people who (usually) are professionals, intelligent, whatever.
If you pay, not worth it IMHO.
Thing to remember is this...once you hit 40, there are FAR MORE single women in your age bracket than single men...with EVERY single hook up methodology (save for online ads), women out number men.
As a result, as a single guy you should NEVER pay to meet women. Never.
Both Dinnerworks and Single In The City call me about once every 4 to 6 weeks asking me to attend events for free because they don't have enough men...
(Of course, it helps if they have met you already and know you aren't a total loser, but instead something approaching the type of guy their single paying female clients are looking to meet).
Fill out the Dinnerworks form online, and when it asks to pay, don't...but indicate your interest in learning more. Someone will call. Tell them you are really interested, but...man...it seems like a lot of money. They will invite you to the next event that they need a guy for on the house (the invite will be last minute...you will only get a few hours notice...that is the deal...they need you to fill in for someone who has canceled). Go...dress nice...be nice...charm all the ladies...impress the host. If you hook up, great. If you don't but make a good impression...you'll be asked back...trust me.
Of course, if you are an ugly fat nerdy loser....women can meet those types on their own without having to pay....so no more invites for you.
