A few of the luxury shops in Ginza have cafes inside them. We visited the one in Dunhill. It is a small cozy café with plush comfortable sofas.
I don’t remember the prices but it certainly wasn’t cheap. Although the quality was fantastic. The room also fronts the street with total see through windows so you can watch the outside world going by.
We economized by going over to the department store downstairs where the food hall was and bought some takeaway lunch. We then whizzed up to the terrace level for a sit down lunch. Many departments stores have a terrace level catered for families to have a snack and to keep the kids calm.
An obligatory shot of the ubiquitous vending machines. That quenched our thirst.
