Travel to Rome next weekend and have finally almost decided where to dine. Pierligui, Trattoria di Monti and Checchino dal 1887 are my current choices. I am totally confused as whether to make reservations before we leave or wait till we get to Rome. We arrive on Sunday and plan on having dinner at these places on Monday, Tuesday and Wednesday. Please advise if possible on how I should go about reserving or if I need to reserve.
