We've eaten at this Italian restaurant three or four times during our visits to Buenos Aires, an easy choice since it's located right next to Hilton Hotel. Carletto Ristorantino e Caffetino features a variety of dry and fresh pasta dishes. It's a popular spot for businessmen in suits, but we've always felt comfortable in our tourist attire.
We enjoyed their self-serve antipasto buffet as an appetizer course the other day. The waiter also advised us that two plates, rather than four, would be adequate for the four of us to share, which was a nice touch. We all enjoyed our pasta courses as well, and we'll definitely drop in for lunch again on any future stay at the Buenos Aires Hilton.
