I am traveling alone to Rome in April for a week. I have been to Rome before, but not alone, and I'm a little hesitant about eating out alone and taking up a table for two with just me (I am a woman and not a big eater, although I love Roman food). Can anyone suggest some places to eat in the centro storico that would be appropriate for a single female diner? I would prefer places with entrees at $20 and under, as this is not a trip for extravagant dining. In the US when I travel alone, I just find places where I can sit at the bar and have a meal, but I am not sure I recall seeing much of that in Rome. If it matters, I'm staying between Piazza Navona and the Pantheon, so ideally would prefer places that are within a 30 minute walk from there (including Monti and Trastevere, and maybe Testaccio). Farther afield is OK as I am capable of figuring out the public transit particulars, but prefer to walk to and from dinners. Thanks for any advice!
