Time Out says
An energetic crowd flocks to this Trastevere bar for copious cocktails and beers out on the bar’s terrace.
Located next to a university on the edge of Trastevere, Freni e Frizioni is perpetually overflowing with a young and thirsty crowd. The name means “brakes and clutches,” and pays homage to the space’s history as a mechanic shop. The interior is now a contemporary mix of poured concrete and massive chandeliers, but most people choose to take advantage of Freni e Frizioni’s private piazza to drink outside near the river. Once you get a drink, that is. The cocktails are so meticulously prepared that it can sometimes feel like time has slowed down while you watch each individual mint leaf be ripped into your mojito; though your patience is always rewarded with the chance to sip the night away in a picturesque Roman setting. Besides, you can always opt for a beer to make the wait at the bar slightly less painful.
Time Out tip: The bar serves a vegetarian aperitivo buffet that is free with any drink from about 6pm–8pm on weekdays.
