BOB AND EDITH’S: This tiny place on Columbia Pike in Arlington seats maybe 10 people at its counter and not many more in its seven booths, but it’s always busy, and with good reason. The milkshakes are fantastic, and are served alongside the metal mixing cup (as any good diner should do). Bob and Edith’s also doesn’t force the customer to get a huge meal, which is especially handy for those late-night meals. At 2 a.m., sometimes all you want is one egg and one pancake, and you can totally do that there. There’s always a good vibe in there, with really friendly staff and people happy to be stuffing their faces. —Elisabeth Grant
