Harold's, a New York-style deli in Edison, New Jersey, has a pickle bar. All you can eat pickles with every meal, including breakfast.
What a silly gimmick.
Harold himself told me that he serves 14,000 meals a week. This at a restaurant at the back of a Holiday Inn. At a restaurant that serves a $30 turkey sandwich!
It's pretty obvious that Harold does just fine giving away pickles--no matter how many you care to eat. Not a gimmick at all, it turns out.
