For decades, the crumbling men’s comfort station on Boston Common had been locked, a tomb encasing ancient urinals and rusting pipes. On Monday it reopened with grandeur, housing not restrooms but a sandwich kiosk fit for a king — or, at least, for nobility.
Earl of Sandwich, the chain owned partly by descendants of the British peer for whom the lunch staple is named, has resuscitated the 1920s bathroom for its second Boston outpost, investing heavily to restore the eight-sided, 660-square-foot stand.

At age 77, and struggling to control my weight, I'd welcome more public toilets, and fewer sandwich shops.
Having to relieve onesef may be an impolite subject, but it is not the kind of problem that will just disappear if you ignore it.
They have public toilets not too far from the restaurant.
Yes, nothing better than eating a sandwich outside in the fall and winter.
