400 Gradi Cicchetti is a sleek yet relaxed and informal bar/eatery located right next door to 400 Gradi. Given its origins they have a high quality food menu and a very well stocked bar, along with highly professional yet friend and energetic staff.
I had a lovely experience and would recommend it for an evening out. The setting and atmosphere is such that you could easily have nibbles & drinks, or even a proper meal there.
