Very enjoyable.
The utter bizarreness of the snapshot image of the standoff between the modified monkeys and the preternatural brothers tickled me in all the right, absurd places.
The idea behind the the ever-simmering soup was pretty awesome--one of those little chestnuts you read and think, "Damn, that should have been mine!"
And I too found myself curious as to how this guy finds these mystical restaurants. I like that. He's not shown as some occult investigator or offspring of a mythological deity or anything like that. He's just a dude who likes supernatural food and inexplicably finds these places, as if they are all around us, we just have to know to look for them. I can't remember where I read it (might have been a Poe essay), but someone was breaking down fiction into three categories: a bizarre voice describing a bizarre event, a bizarre voice describing a normal event, and a normal voice describing a bizarre event. I found this story to be a delightful example of the last mode.
