What kind of food? Reza's does a very good, fairly inexpensive mixed persian-traditional buffet on Sundays. I'm not sure if they'll do anything special for easter, but they do for christmas and new years, so it's a possibility.
It's not the best persian in town, but it's an interesting, relatively inexpensive choice with good atmosphere, especially at the Ontario St. location. The Clark St. location would be more convenient as a midpoint, though.
