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. Renovated in 2008 and pretends to be very up-to-date, but not very successful in hiding how 1980s it really is (especially in breakfast, which is average at most). Private pool with most balconies facing it. Some rooms are without seaview or even a balcony. Breakfast 7:30AM-10:30AM. 15min pleasant walk to Cascais along the coast (which is comfortable with a stroller).
