A haven for chocolate lovers. But you had better be prepared to mortgage something dear to you, such as a surplus grandparent, just to be able to afford the merest taste. Note the extra drainage just outside the window of Wienrich and Boettcher. This is to accommodate the otherwise unsightly puddles of drool.
Could the name of the street be a time-corrupted variant of the name of Zephyrus, the God of Slight Breezes? Perhaps a temple might once have stood here.
The street is also where the copy of the Scone of Stone that was - apparently - stolen from the Dwarf Bread Museum on Whirligig Alley was found. It's located in the Dolly Sisters area parallel to Upper Broadway.
