FRANKLIN SQUARE, N.Y.

CHRIS WAGNER was sipping a Krombacher pilsner draft on a recent Friday evening at the Plattduetsche Park Restaurant beer garden here, as his 2-year-old daughter, Emma, sat on his lap. A snack bar served bratwurst, German potato salad and other Bavarian-inspired foods, and six imported German beers were on tap in the adjacent beer hall.

Mr. Wagner, 34, of Lynbrook, pointed out more than 15 family members who had gathered at long picnic tables with refreshments, surrounded by linden trees that sparkled with strings of lights.

“It’s nice to hang out outside and talk and have a couple of beers, because it’s not really a bar environment,” Mr. Wagner said. “There’s a nice mix of old people, young people, families, strollers, kids running around.”

Longtime German favorites like Plattduetsche Park Restaurant (founded in 1939) and Black Forest Brew Haus in Farmingdale (1998) are being joined by new beer gardens. The three-year-old Mirabelle Tavern in Stony Brook opened one this summer; the one-month-old Croxley’s Ale House in Smithtown is waiting for permits but hopes to finish its outdoor space in time to celebrate Oktoberfest.
