My brother and I go to Olimpico on a nightly basis. Helps that I live three blocks away.
Bartenders are super cool and know how to brew a great coffee. Décor is super chill and brings a great look to the ancient building it occupies.
Gelatos are really good and I often bring my little one for a scoop.
Would recommend this to anyone hanging out in the Old Port. You won't find better value for your money, trust me!
