It's located on the route to the Masca ravine, or to Mount Teide via Santiago del Teide, or to Punta Teno... They have delicious coffee (I forgot to take a picture), and they offer gluten-free desserts without cross-contamination, suitable for celiacs.
They have them on a tray covered with a glass bell; today we had carrot cake and chocolate coulant.
They also have sweets in individual containers, like croissants or cookies.
And a gluten-free Toblerone cake, although they told me this one could be cross-contaminated. They seem to be on top of this.
I didn't ask if they had gluten-free ice cream, but they did have sugar-free ice cream.
The staff is very friendly.
There's a small lounge, and also some tables on the street.
Oh! And a little bowl for dogs to drink from, as they're welcome.
