I was about to quote that exact same passage. There's a shop where I live that covers off all factors, most essentially the bar & café, with delicious food and generous pours of beer, wine, and literary-themed cocktails. As a place it borders on, but doesn't cross over into, parody. As much as I've wondered, aloud and via twitter, whether art will ever be as interesting to people as food seems to be these days, I do agree that the bar & café sets this place apart from any other bookstore besides a select few in the city.
That looks like a nice, quaint, little place. Do you eat there often? I think a book store that had a full bar and served prohibition era cocktails and sold books from that era would do well these days. I would probably curse it under my breath while guiltily enjoying my Gatsby and Corpse Reviver #1
