Endless summer

FOR DRINKERS
* The Sky Room: The swanky rooftop bar, sporting 360-degree views of Manhattan and the Hudson River, is set atop the 33rd and 34th floors of the Fairfield Inn & Suites by Marriott Times Square. Its retractable awning is perfect for some late-summer rooftop tippling. Try signature cocktails such as the Dragon Flight ($15), a concoction made with Bacardi Dragon Berry.

The Sky Room, 330 W. 40th St., between Eighth and Ninth avenues; 212-380-1195. Open year-round. Skyroomnyc.com

FOR ARTISTS
* Art in Odd Places: For this annual public arts festival along 14th Street, 30 artists created work based on this year’s theme — “chance” — encompassing luck, randomness, risk and more. Expect site-specific installations, video and audio projects, performances and other exhibits, all with the same goal of changing how the public views art and how it interacts with city living. Don’t miss “Luck Be a Lady” by Maya Suess, in which the artist will station herself on 14th Street with two women holding the sign: “Luck Be a Lady: Offering Luck. Free” and bestowing luck on pedestrians.

FOR SHOPPERS
Mad. Sq. Mark't: Returning for a second year, this shopper's delight brings 60 vendors selling local, handmade wares ranging from clothing and jewelry to pottery. Parents will want to mark their calendars on Oct. 16 to attend the market's free fall kids festival, which will feature a pumpkin patch, costume parade, pumpkin carving and more. Check out the centrally located food plaza at Worth Square (adjacent to the park), selling food from top restaurants such as Fatty Crab, Hill Country Barbecue and Roberta's Pizza. "It's a fantastic hangout place," says Eldon Scott, president of Urban Space, which organizes this market as well as the Union Square holiday market. "[The park] really transforms once we put the food booths up — it creates a great piazza. It's almost European."
