From Lisbon, take the A2 going south and within 40 minutes take the exit to the beautiful city of "Alcacer do Sal". Near the riverside, you will find a perfect place to a traditional Portuguese meal. The restaurant "Hortelã da Ribeira" has a diversity of great meals. My favorites are "Canja de espinafres com garoupa", "Açorda de espinafres com Ameijoa" or "Bife de alcatra à Descoberta", but many more traditional meals are available. The staff is very friendly and the prices are great for this kind of quality ingredients and great cooking. The typical Alentejo herbs and condiments are used with mastery. The restaurant also has a great selection of wines (the affordable "Casal Freitas 2009" is perfect in both red and white flavours) and desserts something to die for. Truly recommend this restaurant.
