Heres a good option for your Salsa Mondays 909 Sports Lounge in Rancho Cucamonga. I was there a month ago (Dec. 12, 2016) and took these pictures with my phone. Stuff happened and Im just getting to them now, but lets go with better late than never, shall we? This is a nice place with lots of room to dance and to hang out. Theres a Salsa class by Esther Garrison that starts at 8:30 p.m., and social dancing follows with recorded music selected by Ralph Lardizabal. Theyre committed until midnight, but when I was there the music and the dancing went on for a while longer. Theres no cover at the door, and parking is plenty and free. If you are in the Inland Empire, or if you are in a driving adventurous spirit, this is a good place to check out. The address is 11849 E. Foothill Blvd, Rancho Cucamonga CA 91730. More Info below.
