I once heard that Japan is the land of milk and honey . . . on pizzas. Thankfully, this is not the case at Mercato. The only unwanted topping to feature on chef Chihiro Togo's pizzas is sweet corn, which is best served where it began — on the cob. You can't blame the Japanese for sweet corn on pizza, though, my own homeland of Ireland (another great pizza country) is awash in sweet corn-infested pizzas.
