Maybe this is news to no one but me, but Gambero Rosso has issued a new guide for Low Cost restaurants, I suspect arguably competing with Slowfood
Osterie Guide and complementing their more expensive Restaurant compilation
Its a slim, long book, attractive for travelling and not very expensive itself
I got it here http://www.ibs.it/code/9788889711774/... -
The same source sells the Slowfood books (which Slowfood will not ship out of Italy) , tthe whole Gambero Rosso line, he Micaela Scibilia Venice guides (she has a new one for Murano btw) and many , many other interesting things.
