Hello, we'll be taking a train from Florence to Rome on a Saturday. We're staying at Hotel Raphael (Piazza Navona). Can you make a suggetion for a wine bar or cafe where we could get a great panini or other simple lunch? It needs to be a place that won't require reservations, as we don't know the exact time we'll get to the hotel and drop off our luggage. We'll be making our way to the Pantheon, so anywhere in that general area would work, too.
I'll add that we're having dinner that evening at La Pergola. So, I'd like to keep it casual and lighter for lunch.
