Any restaurant with a day of the week specifically devoted to M&C deserves your respect, but Golden Beetle in Seattle is worthy of downright unbridled admiration. Start with a pitch-perfect bechamel (spiked with either garlic or harissa), then choose your own cheese-venture (white cheddar, smoked Gouda, Gruyere), and if you're going all-in there are plenty of choices of protein (local bacon) and veggies (kale, of course).
During the eight-month Boston winter, there are few things better than trudging in from the windy cold hell and going subterranean to Downtown Crossing's beloved Silvertone, getting yourself a booth, a beer, the Weekly Dig, and ordering its famously intense, creamy mac & cheese. They give you a variety of options to top it, ranging from peas (NOOOO) and steak (nooo?), but the only real move is to get it with bacon, and ask for some hot sauce, or -- if you truly want to spend the winter only wearing snow pants -- that Tabasco butter sauce they give you with the jerk chicken.
