A standout on the pedestrianized Rua Amarela strip, Cantina Clandestina serves delicious tapas, light meals, and cocktails (try the Clandestino, which combines gin with lemon, basil, and ginger beer) to a relaxed crowd. You can take a seat in the cozy confines of Cantina Clandestina itself, at sister restaurant-bar Taberna Clandestina across the road, or arrive early to grab one of the much-coveted tables on the famous yellow-painted street itself.

Enjoy colorful salads, seafood, and other light meals with a view over Cascais Bay at this laid-back restaurant-bar in the center of town. Sharing plates and a lively musical backdrop make for a sociable atmosphere, and the sea breezes blowing through the open windows keep things fresh on hot days. For the best views, book a table on the terrace.

Fresh fish and seafood fill the menu at this relaxed restaurant filled with lobster traps, fishing nets, and other maritime-related artifacts. The bacalhau assado (baked salt cod) is one of the specialties of the house, but there are usually also one or two vegetarian options, such as a pasta with tofu and mushrooms.

Popular though it may be, this longtime favorite remains an unpretentious and inexpensive option for its spectacular food and friendly service. Including much more than the seafood found in most local eateries, the menu features dishes from every region in Portugal.

In the heart of old-town Cascais, Santini Cascais has what many people consider to be the country's best Italian-style gelato.

One of several well-established seafood restaurants in town, Beira Mar has won a string of awards for its fish and seafood. An impressive glass display shows off the best of the day's catch. The just-caught local fish cooked on a charcoal grill is always a crowd-pleaser.

This vegetarian and vegan café has a wide-ranging menu that includes snacks and sharing plates, as well as a hot and cold meze-style buffet. Smoothies, juices, teas, coffee, sangria, and beers are available.

There are plenty of other pizza joints in Cascais, but locals will tell you Caffe Itália is the best of the bunch. In its indoor dining rooms or on its sunny terrace you can choose from a range of authentic thin-crust pizzas and fresh house-made pasta dishes.

The Portuguese have a sweet tooth—not a morning, or afternoon, goes by without a stop for a coffee and pastry—and this traditional little shop, with its wide selection of tarts, cakes, biscuits, and croissants, is a great introduction to typical Portuguese sweets. It's also a good spot for a light breakfast.
