I have travelled and lived in Europe and these are my favorite guides...
I love Rough Guides. They are great about including history/culture and are pretty down to earth about what is worth the price. For places to eat I like Lonely Planet. They have some great off-the-tourist-track places in a variety of price ranges. Frommers has some good info as a secondary resource. Personally I can't stand Rick Steves, but I am more of an independent traveller. If you are looking for tell-me-what-to-see-but-I-don't-want-to-follow-an-umbrella tours he's good for that.
