The Sentinel, a neighborhood rag that serves the northern-most portions of Stumptown, gave PVR a nice mention in a recent article that describes the closure of both Veganopolis and Nutshell.
Nutshell was probably the closest thing Portland ever had to vegan 'fine dining.' I think its downfall began when it was discovered that a restaurant owned by the same guy in PDX persistently serves foie gras. Then Nutshell stopped being 100% vegan. When I did dine there once, way back when, I enjoyed the Jamaican platter that I got, but I wasn't dying to go back, despite having high expectations.
Thanks to the Sentinel for the mention! And go visit Proper Eats, probably the best vegan reuben in that part of town.
