It's a pop-up milonga, hosted by Anna Snider and Ryan Hahn.

Anna says:

The only response to a long, cold winter is more tango! Join us for another magical milonga at Eno Vino Downtown! Thursday, February 19th from 7:00-9:00 PM. 

Eno Vino is at the AC Hotel, 1 N Webster St, Madison. Take the express elevator to the 10th floor where you'll find the coat rack and the bar. Then make your way down the staircase to the 9th floor lounge and get ready to get blown away by DJ Ryan's dulcet tunes. This month's milonga will have an extra festive air because it is a week of many birthdays in our tango community. You know who you are! Come join us!
Street parking is free after 6:00. The North Capitol Square Garage is just a few dollars. Milonga entry is $5 by cash, Venmo or Zelle. 

Abrazos, Anna
