From the outside this looks like a convenience store, but there's more inside, so definitely worth going in.
On Fridays the studio offers Colombian-style Salsa lessons, starting at 8pm. For $10 you get the 1 1/2 hour lesson plus light refreshments. It was pretty fun. If you know the other style of Salsa, mainly what we do in clubs in most major cities, you will find it's a little different. It's got an extra step in it that I wasn't used to. But the lesson is fairly simple to follow along. Otto does teach the lesson in Spanish, but it's really learn by watching, so you should be ok even if you don't know any Spanish. And there's always someone that speaks English if you are really stuck.
Wear comfortable clothing, and prepare to sweat. A lot!
Awesome class.
