According to their menu, it's "Sautéed artichokes, romas, scallions, and mushrooms, tossed with ricotta-stuffed tortellini in a pesto cream sauce. Topped with mozzarella & cheddar cheeses and baked to a golden brown."
I think that description is not misleading, and that the dish tastes as good as it sounds (reads?). I really miss Addison's, not just because of their food, but also because it was a common place for us grad students to hang out and get drunk (particularly during happy hour).
