lol @ ummmm. :-0
What about single parents clubs, pubs, bars, strip clubs (joking!)
As for the best places - anywhere that an activity predominantly male takes place. Rugby, Football, Cricket matches, motor sports venues, motorbike rallies. DIY stores supermarkets (think of all those single guys wandering around buying their shopping, just waiting for the chance to impress someone with their cooking skills). The knack is to find the single guys, so probably best not to hang about near mothercare or the babay changing station in boots lol
