There were three of us. One said it was the best burger he'd ever eaten (and he wasn't young). We all really liked everything (three burgers and some patatas bravas). He also really liked the wine they served him.
There are a few vegan options, and they also have gluten-free bread.
I ordered the Swiss burger with plant-based meat and cheese, which was delicious. The waiter was very friendly and efficient. The location isn't bad either, and the price is pretty good, especially considering it's in Cadaqués. It was a Saturday night.
