(CNN) — Romans like their coffee fast, strong and burning hot.
We gulp it down, on the run, sans sitting. Drink and go: that's the philosophy. It's part of the lifestyle, a persistent aroma that envelopes people from morning till after dinner.
Many Romans drink five or more espressos per day. Bars and cafes are our temples. So it's hard to rate the best. The cafes we've chosen are all in the historic center.
We've judged each in the following categories:
1. COFFEE: Taste, smell, temperature, how long it lingers in the mouth, showiness
2. AMBIENCE: Decor, colors, light, mood
3. FOOD: From simple croissants to appetizers and menus
4. SERVICE: Staff competence, friendliness, "at-home" approach
5. LOCATION: Views, proximity to historical monuments and famous places, shopping
Here's what we found:

Coffee of choice: Gran Caffé -- espresso with cream
The owners regularly travel to Brazil to select the best coffee beans from Maya descendants, export the coffee to Rome and pack and sell it to the public.
Everything here is made and smells of coffee: cookies, chocolate bars, cakes, frappes and slushies.
Drinking an average of some 6,000 coffees a day, clients range from politicians to high school kids. Henry Kissinger and Mikhail Gorbachev have had coffee here.

Coffee of choice: Hand-decorated cappuccino or cold cappuccino served in a glass
Owner and barman Luigi Santoro makes the best cappuccino downtown: delicate, tasty and pleasant to look at.
He's a kind of coffee artist, sketching in the coffee flowers, apples and hearts. The cafe, small and snug, serves delicious pastrami pizzas with mozzarella and broccoli.
Serena Roberti, a university student, comes in the evenings. "This place totally relaxes you, the cappuccinos are so yummy," she says.
Perfect for a quick snack and walk, it's located in the popular Hebrew ghetto along the Tiber River.

The master mix is the Queen of Coffees, made from eight Arabica varieties. According to client Maria Rossi, "It's the best cafe in town because it simply tastes of home."

During World War II it was a meeting point for American soldiers. Now it's beloved by Michelle Obama and Sharon Stone.

The coffee here has an aroma that dwells on your taste buds for hours. You can sip-and-go at the shiny wooden bar with artisan floor tiles, or relax outside at the tables facing the area's most beautiful piazza.
Not too elegant, but real cool. It's also a chic "trattoria," a typical Roman restaurant where you eat like a local.

We're going to cause a few arguments, but this is our top pick.
Coffee of choice: Espresso.
Tradition, location and treatment make Rosati cafe the best coffee bar in Rome. It enjoys the best view of Piazza del Popolo with the Pincian Gardens above. The espresso is bliss in a cup.
The wrought iron tables outside and sophisticated coffee room with old wooden decor and marble floors of the 1920s create a warm ambiance. There's a colorful pastry area with some of the best tiramisu in town.
The owners are always there to greet you. It's right in front of Canova, but many coffee addicts claim this serves a far better cup.
