Forget your jumped-up truffled mashers, your milk-and-cookie menus, your comfort food in all its gummy incarnations. That fad is played out, and good riddance. What's replaced it is a focus on those uncomplicated culinary pleasures that -- when done well and treated with respect, rather than tongue-in-cheek smart-assitude -- can bring more actual comfort than a hundred gallons of gussied-up beans and weenies. The best among them? The grilled cheese sandwich. At Chedd's, owners Dirk and Wendy Bruley have made this modest sandwich an object of gustatory worship. Grilled cheese is all they do at Chedd's, in about 17 billion combinations. On the chalkboard behind the counter, they've listed twelve kinds of bread, over thirty kinds of cheese, eight meats, a dozen varieties of vegetables and spreads, and assorted condiments, which you can mix and match for the grilled cheese sandwich of your dreams.
