As someone addicted to buying cookbooks, and frankly in love with New York, this was a must-buy for me.
The presentation is fantastic - the illustrations are wonderful and the recipes are well laid out and easy to follow. The book is neatly punctuated with stories and history lessons, and I'm making the effort to read these rather than skip over and simply gawp at the recipes. This adds a depth of personality that cookbooks often lack.
Some of the ingredients will naturally be hard to find in the UK. This is understandable and completely forgivable. While it's not difficult to imagine what substitutions might be made in most cases, it's something to be aware of.
Additionally, many of the recipes derive from others, so instructions might read "make the x ice cream (on page y)". This is a good way of optimising the level of content in the book (rather than repeating near identical recipes), but it might irk people who like to have recipes that read in a strictly ordered and independent manner.
However, these are very minor points in a book that otherwise delivers on my expectations.
