This should be right up this group's alley! The 5-Boro Bicycle Club is doing their popular Empanada ride, which will start from City Hall in Manhattan and head out to Corona in Queens for some delicious empanadas, but along the way there will also be stops at Grimaldi's for breakfast as well as the Lemon Ice King for dessert after the empanada lunch, before riding back to the start point (City Hall). NYC Cycling & Food indeed, you will likely eat more calories than you burn on the ride. :-D
Figure about 6-7 hours max for this ride, accounting for the foodie stops.
The 5BBC welcomes non-members to its rides, and they are free (you do have to pay for your own food though, of course). Their only requirement is that you must wear a helmet to join their rides. No helmet, no ride, no exceptions.
