GOWANUS CHERYL, the outrageous costumey dance party that has a monthly residency at the Bell House, is departing for a European tour soon. Before they bring their disco, electro and new wave mix to London, Lisbon, Berlin and Barcelona, they’ve got a Euro-themed party in store on Saturday. The costumed/non-costumed ratio is about 60:40, so you don’t have to find a Beefeater hat-combat boot-combo to wear, but it’ll be more fun if you do. Doors 11, $10 all night.
