The classic French restaurant that has been a Main street fixture in Vineyard Haven for 37 years, will come under new ownership this fall. Susan and Stephen Bowen, who own the Waterside Market and Blue Canoe Grill, are the new owners. A closing is planned for Nov. 28.

After 35 years as chef and owner of his signature, classic French restaurant in downtown Vineyard Haven, Jean Dupon has put Le Grenier on the market.

“I love what I do, but I’ve had a good run,” Mr. Dupon said this week. “I just turned 69, I think it’s time for me to start relaxing a little.”

The restaurant will be sold along with its downstairs partner La Cave du Grenier. The asking price is $1.6 million for both the business and the two-story building. The restaurant went on the market in late August.

The enticing aromas of mussels marinière and tilapia dieppoise wafting up Vineyard Haven’s Main street beckoned several dozen customers into Le Roux on a recent Wednesday to witness master chef Jean Dupon, owner of Le Grenier, work his magic.

Is your cream sauce lumpy? Does your hollandaise curdle? Head for the Chilmark Public Library’s free winter cooking classes, Mastering the Art of French Sauces.

Featuring Le Grenier’s Jean-Marc Dupon, the series will begin Wednesday, Dec. 3 at 6 p.m. at the library.

Each class will include a demonstration, tasting and recipes for a different, classic French sauce. Mr. Dupon will demonstrate how to perfect the basic sauce, and how to adapt it with herbs, spices and other magic.
