The Big Oyster: History on the Half Shell

I read Mark Krulansky's Salt about 15 years ago, so I had high expectations for The Big Oyster.  That's probably why I was disappointed.  More a history of New York City (to which as a Philadelphian I am naturally resistant) than of oysters, I found it interesting but not as engrossing as Krulansky's earlier work.   Starting with the importance of oysters to Native Americans and running through the Gilded Age into today, the book didn't tell me anything I didn't know about history and not enough of what I wanted to know about oysters.  Well written and researched, it just didn't grab me.
