Hamburgueria do Barrio

The first location of the local chain Hamburgueria do Barrio opened in 2012. So taken are the residents of Lisbon that there are now multiple outposts all over the city. The menu in all of them has the same 15 burgers (four of which are vegetarian) and feature unusual and tasty toppings like watercress. The double-decker construction—where a middle slice of bread separates ingredients to avoid sogging—is inspired.
