The location is just Cave of the Nadir (as in 'Welcome to Cave of the Nadir, delicious friend!').

This Route is a little different than other routes - there's now a storylet in the Forgotten Quarter letting me go there (well, once my Irrigo dies down) - but it doesn't appear on the map. So while it's in the Route category, it behaves more like other story categories. You could do as you would for those (same category tag for unlock and gain), or make into an item.
