You’re going to want to head to this cozy little bistro for Portuguese specialties: Leitao excels in meaty street-style sandwiches, piri piri chicken, and a Porto specialty called the francesinha, a must-order melted cheese and steak sandwich dripping in a savory tomato and beer sauce. Don’t skip the wines (the list veers organic and natural) or dessert — this is the place to get pasteis de nata.
