There’s a great 26 euro weekday lunch service including a glass of wine. If you cannot be there for a weekday, you can also enjoy their a la cart. They open at 13:00, so if you would like to sit by the window looking at the beach through a garden in front of you with a train passing by, I recommend that you go there 20-30 minutes before opening to make sure that you get a table. May I also remind you that you need to book in advance.
The staff are well trained, which is a great plus.
The interior is funky and what I like about the restaurant is that the space is being used well meaning that it is not cramped.
