Paint the town — or at least the patio at Cinquecento — red during their second annual Rosso Party. On Thursday, June 7th, it’s time to raid your closet for something scarlet, crimson, ruby or cherry, and head to Harrison Ave. in the South End. Arrive at 6:30pm for the best selection of small bites and cocktails, plus you’ll be able to claim your spot for a prime view of DJ Saucy Lady. If your outfit really wows, you might be in the running for a sweet prize — “Best Dressed” gets a tasting dinner for four. Call 617.338.9500 with questions, and see who else is going on Facebook.
