They were very good and had a little menu of what was “sin gluten”. The sandwich bread wasn’t the best I’ve ever had, but it was deff still good. I had the bacon cheese and bbq sandwich! I’d go back. Good price too!
Celiac menu, basically grilled cheeses and meats on sandwich bread. It's grilled in parchment paper to avoid from cross contamination. Sit down or carry out. Reasonably priced and there are lots of locations in Madrid.
