Time Out says
Tropical Burger serves comfort food anytime – they’re open until 6am on Fridays and Saturdays and close half-hour earlier during the week. When it comes to the menu, you’ll not only have “francesinhas”, Porto’s typical sandwiches, but also burgers, Italian food (lasagna, calzone or pasta), hot dogs, and other calorie-loaded options.
