Portugal recommendations

Hi guys,

at the turn of February and March, I’m planning a trip to Porto and Lisbon.

I’d love your recommendations on where to find the best filter coffee in these two cities, ideally at places with their own roastery. I’m also open to those that use other Portuguese roasters.

I’d also like to buy some beans for home. While traveling, I’ll be using the European Coffee Trip app, but there are so many cafés, and I’d hate to miss out on a hidden gem. Thanks a lot!
