On our last night of a week in Munich and staying an extra night as we did not want to travel on our 39th wedding anniversary, we selected Monti Bistro based on Trip Advisor reviews for a nice Italian dinner. We called and made reservations and took a taxi from hotel to restaurant. After being seated, the server came with menus and said, I want you to know that we do not take credit cards which very much took us by surprise. She then said - but not very convincingly - that their credit card machine was down. Being our last night in Germany, we had only enough euros for airport trip in the morning. Thus, we asked if they could call us a taxi (which they kindly did) and we returned to our hotel. While I cannot comment on the food, service, etc. I can suggest that when someone calls to make reservations, they be told that Monti Bistro does not take credit cards - whether it is for one night or standard practice.
