let's call them "map guides"
There's a new breed of city map that combines basic street layouts with information typically found in books-- restaurant prices, museum hours, and nightlife options. Some are more successful than others, but it all comes down to your particular needs. Here are examples from the best series.

Streetwise Maps' Streetwise Vancouver and Artwise London ($5.95) Accordion-folding, waterproof board map with parks, hotels, and points of interest clearly marked. Artwise maps list hours and collections for galleries and museums.
