A bar or a club where there are plenty of Cougars to be found out on the prowl on the weekends. Often a place where a good live band on the weekends and younger men hang out. It can also be a bar that caters to the office crowd at lunch hour on the weekdays, the Cougars will come back to the same familiar place to party for happy hour or on the weekends.
The Sticky Wicket Grill on South Broad Street in Hamilton, NJ is a Cougar Den because it's close to the state offices of Trenton, which is where a lot of the Cougars in that area work. When one of the better local cover bands are playing, the place is packed to the walls with Cougars and Cougar Cubs on the prowl!
