As any serious bibliophile will tell you, the first mark of a good used bookstore is the presence of dust: The more you feel like running home for a shower after digging through its stacks, the greater your chances of scoring a true find there. So try not to hold Eutopia's well-lit and neatly scrubbed interior against it -- plenty of out-of-print titles abound, from K.S. Karol's still-unmatched field study of Castro's Cuba, Guerrillas in Power, to a wall's worth of collectible photography tomes. Although shop hours are slightly truncated (2:00 to 9:00 p.m. Tuesday through Sunday) and there are other formidable used bookstores around South Florida (Kendall Bookshelf continues to impress and Robert A. Hittel, Bookseller is well worth the schlep up to Fort Lauderdale), there's still something delightfully perverse about this oh-so-idiosyncratic tribute to the literary world being located just off the now-defunkified Lincoln Road, within spitting distance of the Gap and Williams-Sonoma.
