I went with my wife and children to VIPS in Neptuno and we had a great experience. We were welcomed straight away by a lady who brought us to a table. She was super nice. This was also followed by a lovely waitress (Yasmin) who took care of our order.
Two of us are coeliac, and their gluten-free good was so tasty. I would recommend the gluten-free Vips classic.
We were impressed how careful they were with the gluten free dishes (i.e. individual table mats of specific color for coeliac customers, plates of different colour too and so on).
Yasmin was so nice as she was checking a good few times that everything was alright. She was not just doing it with us as we had a food intolerance, but with all other customers, and this was on a very busy Easter Friday.
We will definitely come back to VIPS in our next visit to Spain.
