I've just planned a very last minute solo vacation to London and Italy. I'll be
in Rome for a few days and travelling toward Bologna for a food adventure.

Given you're on a budget (think backpacker in a hostel), where would you recommend for London and Italy?

I like good authentic food. Often food stalls and underground/back alley restaurants are the best finds. Do you have any great hidden gems that tourists don't know about and make you truly feel like a local?
