I went already, at least, three times to this restaurant. Always to have dinner.Cais D 4 is placed in a little street in Leça da Palmeira, facing with another restaurants.It's really a little restaurant, but it has a very nice decor with several beautiful and distinctive elements.... the chairs, the sofas, the lamps, the lights, the tableware, the mirrors... everything was choosen with a great sense of harmony and beauty. Nothing was left to chance here, and you will feel very comfortable in this space.The service was nice and helpful. On the last time I went there (yesterday) it was the daughter of the owner of the restaurant who served us. She is a courteous lady.On the other times, that I went there, it was a waiter who attended us. And he was, also, very professional.About the food: the menu has an average number of options, between starters, main courses and desserts. It have a bit of everything and it's appealing.Yesterday, we had the Porto Restaurant Week Menu. I had pumpkin soup with asparagus, for starter, chicken gratin in the oven with potatoes and sautéed vegetables, for main course, and tart tatin with pear and nuts icecream, for dessert.The pumpkin soup was good but it was almost cold. The chicken was delicious!!! It had a different spice, which was really tasty!!The dessert was normal.Overall, it was a good meal, for 20€.On the other times I went at Cais D 4, I ate always from the menu and the experience was very good.I enjoy this restaurant and I will return more times, here.
