Just FYI it is cash only, and they have a bunch of rules plastered on their windows. Then the staff are not very friendly, they seem like you are inconveniencing them. There are plenty of gluten free options in Porto, just need to look a little bit. Tasquinha do Be is GF, and across the river is an awesome GF bakery called Padaria Celicias that is totally worth the 15 minute Uber drive; they have nata, pies, donuts, and more! My wife has celiac and we had no problem finding plenty of other spots that she could enjoy.
