Despite being a time-honored comfort food, the humble grilled cheese is hardly known for its complexity. There is, however, potential for delicious versatility. Combined with the endless variations inherent to mixing cheeses and breads, added ingredients allow for enough flavorful combinations to entice even the most demanding foodies. The Twin Cities Grilled Cheese Festival offers three hours to sample the inspired creations of local chefs and restaurants. An all-inclusive ticket encourages attendees to try a full range of sandwiches before voting on favorites. Organizers have had the foresight to include an open bar with the price of admission. Proceeds will be directed to Heart of America, a group focused on contributing curriculum resources and technological tools to under-budgeted schools across the country. Whether your tastes tend toward classic cheddar melted to molten perfection or more unorthodox combinations, this festival aims to expand expectations of a savory favorite. 21+. Sessions are at 12:30 and 4:30 p.m.
