Belgo Centraal

In the heart of Covent Garden, waiters dressed as monks scurry around the cavernous basement dining hall of Belgo Centraal serving pots of mussels, platters of spicy sausages with mashed potatoes, and halved spit-roasted chickens, accompanied by Belgian beers. Any one of those dishes, plus a drink, costs $13 until 5:30 p.m.; another (limited) menu, good between 5 and 6:30 p.m., lets you pay whatever the clock reads when you order.
