Hi Diane;
The name of the place is: That's Dancing, website: www.thatsdancing.net It's on Route 1 about a mile off Rte 32.. We probably won't be going back until the second week of December. On Mondays in December they're having group tango lessons for beginners on Mondays from 7:30 to 6:15.
Anyway, take a look at their schedule of activities on the website and maybe we can go together in December sometime.
