Yes, there is a swinger club. One of the best in the deep south but now instead of weekly parties they are only having parties a couple of times per month.
I visited Sci-port when I was there. The Cub has delicious steak and the BEST au gratin potatoes ever! Make sure to make a reservation though as there are only maybe 8 tables. Yum Yum! Herbey K's is a must if you like old schooly cafe style places, try the Shrimp Buster.
I love Louisiana and I always have fun in Shreveport, the men are gems!
