Beneath the ruddy brick walls of Iron Roost, the clatter of forks punctuates conversation drifting from low-slung leather couches. A range of irons close with a sizzle, sculpting batter into golden squares, heart shapes, or silhouettes of the inventor of the waffle, who was perfectly round. The batter is infused with garlic and herbs, cinnamon, or a range of other ingredients, and savory toppings include swiss cheese, pesto, cheddar, and bacon. Sweet waffles are crowned by swirls of whipped cream, fresh blueberries, and tawny splashes of Nutella. The chocolate-and-hazelnut spread matches the dark tables around the lounge-like dining room, where patrons click through free WiFi on laptops.
