I had to stop and take a snap after emerging from the stories-deep, gleaming-clean, efficient-and-cheap Metro and seeing this. To be fair, my lunch hostess the next day did say the place is wildly popular. She won’t go back, though, because “they’re too friendly — you walk in and eight people want to help you.” And that’s from someone who lives in a city where, when I couldn’t find a particular restaurant, I stopped in a graphic arts gallery to ask for directions and the mailman who happened to be dropping off letters insisted on walking me to the nearest corner to point to where it was.
