Elm Shakespeare Company’s 23rd annual production in New Haven’s Edgerton Park is one of those things you must do once (or every year). A summer night, a relaxed crowd on the Great Lawn in the Center of Edgerton Park, a little food and beverage of your choosing as the company performs Shakespeare’s timeless words on a cool set.

This year’s play, “Love’s Labour’s Lost,” marks a return to less well-known plays (after last year’s “Romeo & Juliet”).

The plot: The King of Navarre has sworn to give up all pleasures of the world to study, says an Elm Shakespeare description. But when the Princess of France arrives on business, frivolity triumphs over drudgery and the whole town erupts in pursuit of what (and who) they love. Complications ensue, of course, along with riotous mishaps by quirky characters, and a price must be paid for true love.

Some tips about the park: Go there an hour or so before the 8 p.m. show to picnic. You can bring just a blanket and sit in the front or bring camp chairs. Parking is on-street along the large square of the park’s walls (inside parking only with handicap permit). Bring food and beverage but ice cream and kettle corn are available most evenings. Candy, sodas and water will also be on sale this year. Well-behaved, leashed pets are welcome. The shows are fairly kid-friendly, too.

Edgerton Park, 75 Cliff St., New Haven (off Whitney Avecue at Hamden border). Tuesday-Sunday, Aug. 16-Sept. 1, 8 p.m. Free. Elmshakespeare.org
