I have used many Dorling Kindersley gidebooks and they are all visually stunning.
This one is exceptional though. I love Belgium - if you like interesting history and architecture and decent food (and chocolate!) or are "into" lace (!?) then Belgium is the place to go. the fact that you can see Bruges, Ghent and Brussels in a long weekend is a real draw for me.
This volume - exceptional value at less than £7.50 is all you will need for the four cities on the cover. It's only Antwerp that I haven't been to with this guide - yet!
So, what's inside? Maps of all the important parts of teh cities, history of each area, important places to go with addresses and opening times, places to stay and eat. In fact everything you could want to know and see.
I whole-heartedly recommend this DK book. Go to Ghent and see the castle and the Gothic cathedral. Visit Bruges and go to the Groening museum, the Markt and the Stadhuis (try the Rabbit stew and the Chicken Waterzooi soup they are favulous!) Or go to Brussels where there are too nuemrous places to mention here but don't forget the museums and the Manneken Pis!
Enjoy!
