The loft where he visits nutty pick-up Roseanne Arquette is at 28 Howard Street.
Gone are the days when an enormous loft could be affordable to an aspiring artist who would willingly furnish it with plastic sheeting for partitions and bare lightbulbs.
The River Diner was actually up 11th Avenue at 37th Street. (Now demolished.)
Back in SoHo - more empty streets, since taken over entirely by luxury retail, chain-stores & euro-trash restaurants & bars.
The "Terminal Bar" was on Spring & Renwick Streets. It's now an ersatz "Irish Pub".
A "Jil Sander" boutique can now be found on the right, "De Vera" on the right.
The "Club Berlin" was at 289 Hudson, now a deli.
Somehow, the piles of garbage still remain.
