If you were planning to mooch off of your friends this weekend by not bringing any beer to their Memorial Day barbecues, here’s a far more respectable way to freeload.

Feltman’s, the 100-year-old hot dog brand that preceded Nathan’s and this summer returned to Coney Island six decades after it closed there, is celebrating its return with a giveaway. On Monday, starting at 11:30am, the first 150 people to line up for the boardwalk shack’s grand opening and ribbon cutting will score free all-natural beef dogs, served on a toasted potato bun. Remember: This dog won the approval of competitive-eating champ Takeru Kobayashi himself, who knows a thing or two about scoring free dogs. Then again, that’s probably not saying much, since he’s presumably pretty burned out on Nathan’s after eating fistfuls of them at a time.

If Coney is too far to travel: Duncan’s Burgers, the itinerant burger joint that settled down inside of Bushwick tiki spot Dromedary Bar a few months ago, is serving up 99-cent burgers all weekend. The pasture-raised, dry-aged beef burgers are normally $3.49 (at 3 oz., they’re lil fellers), but prices will be slashed Saturday, Sunday, and Monday. Cheese’ll cost ya, though: An extra dollar, to be exact.

Or, just mooch off your friends at those barbecues. They deserve it for showboating. We get it, you have a nice backyard.
