Ideal for winding down in after a walk along Lisbon's Belem waterfront, the riverside Café À Margem offers down time in sophisticated and minimalist surroundings. While known as a restaurant venue, this strikingly designed shimmering white structure works equally well as a café, and one with a superb view of the River Tagus. Food and drink options extend to healthy and revitalizing natural juices, smoothies and herbal infusions, fresh crunchy salads, bruschetta and cheese platters, and wine is available by the glass. The patio tables are quickly snapped up early evening, especially if the weather forecast predicts a blazing sunset.
