10 Best Restaurants in Baixa and Ribeira, Porto

With a cavernous interior, lovely blue and yellow azulejo tiles, and formal staff, this upscale tasca has been a local favorite since 1939. It serves vast portions of typical Portuguese dishes such as cabrito assado (roast kid) and bacalhau d'ouro (salted cod with turnips, potato, and cornbread). Most main dishes easily serve two, but leave room for something from the ever-changing but dependably good dessert menu.

Make reservations well in advance, as walk-ins often find themselves out of luck at this industrial-chic spot serving inventive renderings of local classics. Its signature dish is an entire grilled octopus easily big enough for two to share, but there are also delicious small sharing plates like quail egg croquettes and tuna tataki.

Portugal's most celebrated contemporary chef, José Avillez, brings his signature flair to Porto with Cantinho do Avillez, a homey yet modern dining room just downhill from São Bento train station. While he's unlikely to be in the kitchen—his food empire spans more than 30 restaurants globally—he designed the menu, and quality remains excellent. Expect moments of inventive gastronomy such as his signature "exploding olives", alongside polished versions of local comfort food like steak sandwiches with garlic sauce and fleur de sel, or creamy lobster rice.

Without a doubt, one of the most heavenly—and budget-friendly—meals in Porto is the slider filled with roast pork and sheep's cheese from this snack bar. Served in a warm country roll and oozing with pungent Serra da Estrela cheese, it's no wonder there are always lines out the door. Casa Guedes now has three branches in Porto, including a trendy rooftop, but the "traditional" branch remains the most inviting.

Founded in 1933, this "musicians' café" exudes an old-world charm. The afternoon tea is famous, and if you're lucky you might happen upon a poetry reading or a live concert (often fado music).

Porto has a growing number of restaurants focusing on vegetarian dishes, and one of the places leading the charge for sustainable meat-free cooking is Época Porto. It's a small, light-filled space serving breakfasts, lunches, and brunches made entirely with organic produce---think barley bowls with mushrooms, goat cheese, and caramelized onion---and there's a range of natural wines and craft beers to accompany your meal.

A simple front entrance hides a spacious, flower-filled terrace out back at this detail-driven café in trendy Cedofeita. The owners pride themselves on preparing nutritious meals that don't compromise on taste or presentation, so expect your brunch to feature, for example, perfectly poached free range eggs on homemade sourdough bread. There's a huge range of teas and coffees, along with sparkling wines and cocktails for those wanting to indulge.

Full of Art Nouveau grandeur—think leaded-glass doorways, elaborately carved woodwork, and ornate chandeliers—the Majestic Café has been the preferred hangout of Portugal's intellectual and social elite since the 1920s. After years of neglect, it was restored to its former glory and is once again an elegant place for coffee, cakes, and evening piano music.

The Foz neighborhood, at the mouth of the Douro, is a favorite place for well-heeled locals to see and be seen, and this smart two-story seafood-focused restaurant has become a neighborhood standby. It's particularly hard to resist the sauteéd tiger prawns, black spaghetti with lobster, and top-grade sushi. The space itself is as elegant and well-presented as the food.
