A bijou, impossibly chic bar across from Hadrian's Temple that feels like an in-crowd secret. This is where Rome's fashion set come to sip excellent cocktails (their bartenders are some of the best in the city) in plush, bear-huggy chairs. You'll find most of the insouciant clientele wrapping their lips around the signature spritz, mixed with homemade ginger beer and a bitter liqueur made with rhubarb, in place of straight Aperol.
42 Piazza di Pietra, Pantheon
You'll find this contemporary bar-restaurant in the shadow of Rome's old gas plant – and, like most drinking establishments in a formerly industrial area, it's super hip. Their spritz cocktail is made with violet liqueur, lychee and prosecco, and pairs nicely with plates of carciofi alla giudia (fried courgette flowers) and supplì (rice balls).
38 Via del Gazometro, Ostiense
Punters spill out onto the pavement at this fiercely-loved bar that serves signature cocktails and artisan beer. Their knowledgeable, friendly bartenders happily mix the Ulisse spritz, made with grapefruit, basil and cinnamon.
133/135 Via dei Volsci, San Lorenzo
This gourmet deli in quiet, residential Parioli may look like your run-of-the-mill grocers when you walk in – but be sure to take a look at the back, where you'll find Rome's only vermouth bar. Pull up a stool and order the mighty fine Gipsy [sic] Spritz with grapefruit, ginger, lime and a generous glug of prosecco.
184 Viale dei Parioli, Parioli
Sip on a ritzy Purple spritz made with honey and ginger liquors and prosecco in this traditional bistro around the corner from the Trevi fountain. The interiors at this brasserie-cum-cocktail-bar are just as wonderfully highfalutin as their drink names, all red-leather booths and polished wood.
23 Via delle Muratte, Trevi
