Christopher’s is California-casual, with large windows overlooking North Wayne Avenue, plus exposed brick walls and terra-cotta-colored walls. Sure, you’ll spy young Main Liners on dates at the bar, but most tables are filled with parents and kids enjoying the $5-and-under children’s menu. The friendly wait staff is trained to serve quickly—a kid necessity—and menu choices include pasta with butter, hot dogs and Jell-O. More adventurous eaters might try a pizza topped with caramelized onions, Granny Smith apples and mozzarella with a balsamic reduction. Adult-size entrées are $11 to $20 and range from meatloaf to vegetarian lasagna to grilled whole fish.
