There are a few must-try restaurants located around Lisbon and totally worth trying. If you feel like a half-day trip, feel free to use some of these great restaurants as the excuse to escape Lisbon city center.
All drive times are approximate, starting from Downtown Lisbon.
Within 30-minute drive, you will reach Cozinha Velha. This restaurant is in the Queluz National Palace, and serves traditional Portuguese dishes, their specialty is the Sunday "Cozido" lunch where you experience the most traditional Sunday feast.
Taking a boat ride to cross the Tejo river to Alamada, you will find Ponto Final, a lovely rustic restaurant sitting at the waterfront patio offering classic Portuguese plates and an uninterrupted view of the river and Lisbon city.
Staying on the Almada side, you have to explore various restaurants and bars on the Caparica beach. One of my favorite beach restaurant is Irmao, it has a chilling free vibe and sometimes has DJ and live music.
Driving 30 minutes west towards Cascais direction, you must make a stop at Furnas do Guincho, where you can enjoy the fine seafood and just simply the wavs and the sea from this elegant restaurant on the cliff and rocks.
Keep driving north all the way to Sintra mountains, make sure to check out Moinho Dom Quixote. It is a windmill turned restaurant now has lovely garden, an out-of-this-world view of the ocean and villages, truly a work of art.
