Some of my favorite destinations are unmarked: L'Express (perfect bistro) in Montreal, the Paramount Hotel in New York, certain police cars . . .
And today, the little jewelbox location of Manolo Blahnik, on 54th St, across from (the other side of ) MoMA. I'd been strolling along, looking at the pub where Mona Simpson tried to have a cup of coffee with her interviewer, and a few doors down, there it was! A simple, clean front with a very discrete plaque announcing its distinguished proprietor.
I didn't go in (had two anxious lassies en route to American Girl, which is decidedly NOT unmarked), but did develop strong feelings for the pumps in the window.
