If you're looking for quirky, well-researched map guides with a personal-touch sort of feel, these will definitely be up your alley. Those at Herb Lester have researched the typical tourist spots in most of their map guides, but went a step further to introduce unique spots you may have never heard of, or feared to try.

They're about £3.00 (so about $4.75), which is a pretty good deal, & should grant you permission to buy more than just one!
