Ah, nothing like a feel good charitable fund-raiser for the holidays. JM Curley in Downtown Crossing has done one better. The neighborhood tavern is sponsoring a “40-40-40-40-40” Challenge: you get a 40-ounce natural ground beef cheeseburger (yeah, it’s big), 40 ounces of hand-cut shoestring fries, 40 ounces of malt liquor - and 40 minutes to polish it all off. Those who finish it all pay nothing, but those that don't get charged $40 (and truthfully, here’s hoping you can’t). Either way though, the restaurant will donate $40 for any of the special toward a local food shelter this holiday season. Hungry? You won't be for long. Click here to be inspired (617-338-5333).
