"Also called l’obitorio (the morgue) because of its vintage marble-slab tabletops, this is Trastevere’s oldest and most popular pizzeria (it opened in 1931). Think super-thin bases, a clattering buzz, testy waiters, a huge street terrace and plenty of fried starters."

Krisanne Fordham

"It’s got cafeteria-style seating, is perpetually packed and always understaffed, but the pizza’s so good that you won’t even care. Though everything on offer is great, the standout pizzas are the margherita and the salsiccia e fior di zucca topped with sausage and zucchini blossoms."

"Be prepared to wait in line or plan to show up early to Ai Marmi: this popular, no-frills joint fills up at lightning speed, but trust us, it’s a favorite among Trastevere locals for good reason. The deliciously charred pizzas and mouthwatering seasonal toppings are 100% worth the wait. The restaurant is a no-muss, no-fuss, authentic Italian experience."

Wanted in Rome

"Yes, it does mean the interior slightly resembles a morgue, but once you dive into your pizza pie, sat elbow-to-elbow with your neighbouring pizza lovers, you soon discover this place serves up a slice of Italian life. Favorites are their Margherita, Napoletana and Marinara, but other combinations like sausage and courgette flower are to die for."

Maria Pasquale

"This popular pizzeria located in the cuore of Trastevere is one of the best when it comes to serving up that perfect Roman pizza: light, thin and crispy crust. It's extremely sought after not only by tourists but by locals themselves. For years, Romans have been calling this pizza joint "l'obitorio" (the morgue) and "ai marmi" because of its characteristic long marble tabletops."

Erica Firpo

"A Trastevere institution since 1933, Ai Marmi (the official name is Panattoni, but no one calls it that) is exactly what you’d expect in an Italian neighborhood pizzeria—zero frills, lots of character, and authentic, thin-crust Roman pizza."

Natalie Aldern Kennedy

"Ai Marmi is a lively traditional Roman pizzeria filled with long marble tables (marmi means “marble” in Italian) that are pushed together in rows to accommodate the crowds that flock to this Trastevere institution for crispy thin pizza. Find a table to the left of the dining room as you enter in order to have a better view of the pizzas being expertly slipped into the wood fire oven."

Brooke Eliason

"Pizzeria Ai Marmi is not only one of the best Trastevere restaurants, but they serve some of the best Roman-style pizza in the Eternal City. Often times packed to the brim, Ai Marmi serves delicious pizza with thin and crispy crust six days each week. Get the basic pizza margherita so you can really enjoy the simple cheese and tomato flavors on your first visit."

Goop

"Taking up a fairly large storefront in Trastevere, this traditional Roman-style pizza spot is an important stop if you’re eating your way through the city. Order off the lengthy menu (we suggest going purist with a Margherita), take a seat at one of the communal tables inside or street-side and enjoy your pie (you eat it with a knife and fork) while watching the pizzas go in and out of the massive oven in the open kitchen."

Fathom

"Every native Roman calls this place L'Obitorio (the morgue) for the large marble table where they make the pizza, which looks like a sarcophagus. (The burning inferno in the background only adds to the dramatic look.) Indeed, the thin-crust pizza is to die for."
