NYC Milongas
Try to make it in tonight. One of the best & biggest regular milongas of the week is "LUNA" at Dance Manhattan, one of the larger (if not the largest) regular dance floors in the city. Also the other great milonga is the 2nd Sat monthly milonga, the All Night Milonga at Stepping Out. Come back for that. Stepping Out also has a large smooth dance floor and the All Night Milonga attracts lots of advanced dancers from a large section of the community. If you're in on Sat and want to tango all day long, check out Mariela Franganillo's practica at Dance Manhattan from 11-2 where the music is good, Mariela teaches two short lessons of nice steps for social dancing, and the crowd is fairly advanced. In my opinion, Mariela is the most elegant dancer in the US. Then go to Chelsea Market and dance for free from about 4:30 to 7:45. Eat dinner, recover, and then go to the All Night Milonga and dance until 5 or 6 am.
For Tuesday, Triangulo attracts the younger crowd. A lot of teachers head there late in the evening. Robin Thomas DJs there. La Boca skews towards an older/couples crowd. When famous performers or local favorites perform or teach at La Boca, it can attract a large crowd, but on a regular night, I'd go to Triangulo over La Boca. Both are relatively small to moderate sized dance floors.
Wednesday is not the best night for tango in NYC. I don't normally go out on Wed, which seems to be a cursed night in NYC. Many milongas have started and failed. Empire has been experimenting with its traditional & alternative mix of music as a milonga for those who like both types of music. I don't have any personal experience on Empire on Wed so I can't say yes or no. Lafayette Grill is VERY hit or miss on Wed. I've been there before, but I haven't been back in a while. I just don't tango on Weds.
Let me know if you're ever in town on a Monday night or for the All Night Milonga so we can dance.
Happy dancing.
