Our favorite links for Parisian food and drinks

If you know Marco and his lab, you'll know that good food and great drinks are what makes life worth living. Here are some of our favorite spots in town:

L'Avant Comptoir, a stand-up only French small plates (kind of like tapas) wine bar and foodie counter in the Odeon district. And the sit-down Comptoir restaurant next door is one of the originals in the New Bistrot movement that has taken Paris by storm.

Frenchie - Restaurant, Wine Bar and To Go, this guy is a genius and all three places are worth every minute spent there.

Le Jeu de Quilles, a fantastic gem off the beaten path, with a small menu, but the owner's love for his art shines through. Near Rue Daguerre in the 14th arrondissement.

Cantine California, there's a traveling food truck and a sit-in restaurant (in the Arts et Métiers district) that makes perfect burgers and tacos.

Johana's Fish n Chips, the closest thing to Queen's approved fish n chips in Paris, run by an adorable Parisian family, in the Montorgueil district.

Le Fumoir, a gentle(wo)man's bar across the street from the Louvre, one of the best places to get American-style cocktails, and a great Brunch.

Le Rosebud, the perfect bar for cold winter nights and warming bourbon cocktails, the favorite drinking haunt of Simone de Beauvoir and Jean Paul Sartre, on rue Delambre in the Montparnasse district.

Hexagone Coffee, the newest addition to the developing artisinal coffee scene in Paris, on rue du Chateau in the 14th.

Loustic Café, a fantastic coffee house in the 3rd arrondissement.

Boot Café, one of Paris' best cappuccinos served from a converted shoe cobbler's shop.

Jean Hwang Carrant Cookies, bringing the best home-made organic cookies to Paris, in the Montorgueil/rue du Nil area.

Trail of Crumbs, a Gastro Travelogue by our friends the Rubi-Dentzels who comb the world in search of really special places, food and drinks.

Paris by Mouth, the go-to guide to good food in Paris.

David Liebovitz, Paris' adopted foodie son who has eyes on everything good and delicious.

The Vignuzzi Lab Country Retreat

Located in the heart of Burgundy, the village of Noyers-sur-Serein is a hidden gem on the official list of France's 100 most beautiful villages. The medieval village, under strict architectural protection by heritage laws, showcases hundreds of 12th to 18th century houses clustered around artisan shoppes and artist studios. Located 200km from Paris, the lab frequently retreats to the country house for summer barbecues and pool parties, or winter getaways and the epic Thanksgiving dinner gathering 50 family and friends. Built in 1491, this special house loves to be shared with our friends and colleagues.
