If you are celiac, $ you pay $
We chose this restaurant in San Lorenzo de El Escorial because it had gluten-free options, both in pizzas and pasta.
The surprise was when they brought us the bill. For each "gluten-free" dish they charged us an additional fee.
They brought us a normal menu and told us that we could order anything on the menu, which they made adapted with Gluten-Free dough or pasta, but nowhere did it say that because it was gluten-free, it was more expensive.
I think it's abuse on their part. It is unethical to take advantage of intolerance to charge more and without notifying the customer of the price increase.
We feel cheated.
