I rubbed my eyes, opened and closed them a few times, but it wouldn't go away, so this wasn't insomniac deliria. The sign in the window said "Ramen Setagaya", and was accompanied by two photos of the trademark shio ramen. No opening date posted. Corner of Prince Street and 37th Avenue, same side of street as Green Papaya Thai, Canton Gourmet, etc, but a block or so closer to Northern.
As a frequent visitor to Japan, and a ramen lover, I was very pleased with Setagaya's product when they first set up shop in the EV a few years back. Haven't been back in a few years, and have heard the reports of declining quality.
As a Queens resident, I'll keep my hopes up for its' own sake, until I have reason not to. We're pretty much ramen-deprived in this borough.
