I just bought it, and will be running it in my campaign, as an Orc city where the warband of orcs (characters in the campaign) will soon call a home city, with built in intrigue and all.  My FLGS still had a copy of it.  So far, the city was nebulous in our game, and I only stat-ed out some bars they went to, to recruit some Orcs and Goblins.
Rating: 
The Prc's are specific to the setting, and look like they will add some flavor.  I think there is a little less layout or maps in the city than I would like for a city book, but I'll overcome that with some layouts of my own.  There are some built in background histories, and legacies that will work nicely into my campaign with only a few modifications.  The Brutal Feat from the book will fit right in with the players' characters.  
Overall more material than I expected in the flavor, background, and Prc's for the city, and fewer maps and place descriptions within the city than I would have liked.  But in contrast it gives a good basis for expanding the setting to a very useful location.
On a scale of 1-10, I'd give it a strong 7, very useful, some extra bits to make up for what I felt was lacking for the good grade.
I hope this isn't considered bad taste here on Mongooses' own boards, if they see it as a bad thing, I'll be glad to delete, and do a full rating on my own board, and only post a link for those interested.

PS I consider 7 a good rating
