Street Smash Burger Cascais

The ever-more-famous Street Smash Burger landed in Cascais in August 2025, after opening its first spot in the borough back in January, in Carcavelos. The menu hasn’t changed – the Street Burger (€9.90) comes stacked with 180g of beef (no preservatives or nasties), American cheese, onions, pickles, ketchup and mustard. You can pile on extras too: more meat (+€3.50), more cheese (+€1.50) or a gluten-free bun (+€2.50). Plus, house sauces like Mayo Sriracha and BBQ Smokey (+€1) are on hand to crank things up.
