I've been dancing Pro-Am in the International Latin style with Leon for about 1.5 years, and so this is more of a review of his teaching than the actual studio (which he is currently setting up as of this date).With private lessons, you definitely get a lot for your money. He is very focused in helping you achieve your dance goals, as long as you articulate it. He'll also introduce you to new dance styles (if you're focused on one style like me). I like Leon because he not only teaches you at the studio, but he'll also connect with you outside the studio - and this speaks to a person who is serious about improving their dance technique like me. He'll check in with you outside of studio time, provide you with dance resources to make sure you get a certain concept right if it wasn't grasped during your lesson, and make you fully understand the culture of dance (if you care for it)! Receiving lessons from Leon is a pleasure because he not only has a passion for dancing, but you know that he really cares about his students.Outside of private lessons, Leon hosts outings to various salsa clubs in Boston and Cambridge (usually it's Havana Club in Cambridge). I don't take his salsa classes, but I've gone out with him and his students and it's always a good time. Lastly, he also hosts a dance video blog (www.passion4dancing.com) where he'll teach certain dance techniques. It's a true testament to his comprehensive teaching style.

I was shocked at how terrible their customer service was. The woman I talked to was very condescending and even told me to go somewhere else when I was just hoping to have a vehicle inspection before driving across country. I am definitely taking my business somewhere else.

negative

Terrible. I ordered a pretzel and Saurbraten. The pretzel was dry And the mustard they served with mixed with Apple sauce. Terribly sweet. Terribly sweet. Then It took 45 minutes to get the Saurbraten. Then when I got it it was so sickeningly sweet that I couldn't eat it. Sugar in the gravy with excessive as well as the sugar in the red cabbage. Spetzel could have been good if it had not had the gravy and theFlavor of the red cabbage mergingWith the spetzel. Great concept but Don't ever order the pretzel or Saurbraten! Complete waste of time and money
