I've been in Lisbon for two weeks and have been using my Wise MasterCard, which has worked fine in other European cities. However, I've encountered two restaurants in Lisbon that refused to accept my card and claimed to only accept "Portuguese cards". I haven't encountered this issue in other European cities and I'm curious if this is a common practice in Portugal. Can you provide any information on why some restaurants may only accept local credit cards, and if there are any specific types of credit cards that are more widely accepted in Lisbon?
How common is it for restaurants in Lisbon to only accept Portuguese credit cards?
