This weekend marks the end of Ramadan, the holiest month of the Muslim year. For Muslims throughout the world, the month has been one of prayer, charity, and fasting from sunup to sundown. A handful of Twin Cities restaurants have been catering to those observing the holy month by offering a special way to break the daily fast -- Ramadan buffets. One of those restaurants, the Marina Grill and Deli in northeast Minneapolis, has become a gathering place over the past month.
