Vesta Lunch (474 Dupont): The food is diner-style bad - rubbery eggs, oily potatoes, cheap bottled juice. But that's okay and after expensive, faux-diners it is always a relief to eat dirt cheap, genuinely bad food in a place that looks like it's supposed to serve it. Vesta is an institution of sorts, skinny and lined only with one long bar where you'll always find Greek taxi drivers congregated on one end, drinking coffee and barking at each other in Greek. It's open 24 hours.
