On Fridays in March, the Four Seasons' restaurant, Park 75, rolls out an over-the-top, all-you-can-eat chocolate buffet, and there's usually a line out the door. The menu includes endless chocolate creations: brownies, chocolate-dipped macaroons and more. $30 for buffet; room rates start at $400 per night; 75 14th St. Northwest; fourseasons.com/atlanta

The 6-pound milkshake here was supposed to be a dessert for sharing, but customers started ordering one per person and trying to finish the shake alone. (It contains a half gallon of ice cream!) Now the milkshake challenge is official: Consume one in less than an hour and you'll join hundreds of champions on the restaurant's website. $18; 165 Main St.; chickandruths.com

This is the place to try an unusual Arkansas specialty: biscuits with chocolate gravy. The dish is exactly as it sounds — two biscuits topped with a sweet gravy made of chocolate and cornstarch. Wagon Wheel is just off Highway 65 on the way to Branson, Mo., so lots of out-of-towners stop in to taste this quirky dish for the first time. $3 for a full order, $2 for a half order; 166 South Broadview St.; 501-679-5009

In the 18th century, chocolate bars weren't snacks — they were a delicacy, intended to be melted for drinking. Back then, turning raw cacao beans into one pound of chocolate could take all day. You can see a reenactment on the first Tuesday of the month from September through June. (Why no summer shows? Experts think colonists likely didn't make chocolate in July and August.) Free admission with $19 to $38 tickets to Colonial Williamsburg; 101 Visitor Center Dr.; history.org

When the Trappist monks settled in the hills of central Kentucky in 1848, they supported themselves by farming. Now they sell fruitcake, cheese and, best of all, homemade fudge.

It's sold online, but we recommend stopping by in person and hiking the abbey's trails. $22 per pound; 3642 Monks Rd.; gethsemanifarms.org

This spot calls its hour-long factory tour a "tasting tour" because you get to try so many treats along the way.

Northeast

No trip to Maine would be complete without a moose sighting, and stopping at Len Libby guarantees you'll see at least one: a 1,700-pound, life-sized moose named Lenny that's made of milk chocolate.
