Monte Bistro, (close to Saboia Hotel), ☎ 466-0106. A restaurant and take-away. Excellent value for money, a good portion of creativity while staying within traditional cuisine. Probably the best option when you lodge in Estoril and don't have time to walk to Cascais for dinner.
Saboia Hotel. 15min pleasant walk to Cascais along the coast (which is comfortable with a stroller).
