When H.P. Lovecraft lived in Brooklyn, he used to love hanging out at the Double-R Coffee House along with other writers and playwrights. The awesome blog Tentaclii dug up a photo of the Double-R as well as some interesting history about it. Lovecraft even immortalized it in a poem. Here's a snippet:
Here may free souls forget the grind
Of busy hour and bustling crowd
And sparkling brightly mind to mind
Display their inmost dreams aloud
— extract from “On the Double-R Coffee House” (1st February 1925)P.S. If anyone knows of a less grainy version of the photo and/or has the Photoshop skills to clean it up, would love to share a more legible version if I can get one.
