Dolce Vita is in the heart of the historic piazza del Carmine, and the building is architecturally interesting to boot! It's got a delightfully weird, hipster-hideout vibe, since the square it's in is much less "buzzing" than the nearby piazza Santo Spirito that's peppered with more frequented "artsy" havens.
You'll be spoiled for choice when it comes to wine and cocktails. DV also has a substantial buffet at "aperitivo" hour (when you pay for a drink or cocktail and can take a plate of food at no extra charge.) Expect to find pastas and real dishes, not just finger foods.
They've got a cozy back room that's great for groups or mingling with new friends you've made in town!
