💡Quick Answer

Of the four Roman pasta classics, carbonara and amatriciana are the safe orders and cacio e pepe is the risky one. Reviews naming cacio e pepe carry a one- or two-star rating 17.8% of the time against 10.1% for carbonara — nearly double. Gricia behaves the same way. Tiramisu is the safest thing on a Trastevere table, and the most common complaint about any of it is seasoning, not technique.

Naming a Dish Is Already a Signal

Before comparing dishes, one control that changes every number that follows.

Across 5,020 rated reviews of three Trastevere restaurants, the ones that name a specific dish average 4.35. The ones that name none average 4.52. Naming what you ate goes with having something to say about it — and people with something to say skew slightly unhappy.

Reviews	Count	Average rating	Share of 1–2★
Name at least one dish	1,535	4.35	10.4%
Name no dish	3,485	4.52	8.2%
All rated reviews	5,020	4.47	8.9%

So the baseline for every dish below is 4.35, not the site-wide 4.47. Measuring dishes against the overall average would have made all of them look worse than they are, and would have manufactured a finding out of nothing.

The trade-off: using the stricter baseline shrinks every difference. What survives it is worth trusting.

The Risk Table

Here is every dish named in at least twenty reviews, against that 4.35 baseline:

🍝 Dish	Reviews naming it	Average rating	vs the 4.35 baseline	Share of 1–2★
Supplì	26	4.58	🟢 +0.23	0%
Tiramisu	457	4.56	🟢 +0.21	5.3%
Lasagna	86	4.49	🟢 +0.14	8.1%
Carbonara	773	4.38	⚪ +0.03	10.1%
Amatriciana	155	4.32	⚪ −0.03	10.3%
Artichoke / carciofi	161	4.27	⚪ −0.08	10.6%
Meatballs / polpette	174	4.21	🟡 −0.14	12.6%
Burrata	103	4.13	🟠 −0.22	13.6%
Gricia	68	4.12	🟠 −0.23	17.6%
Cacio e pepe	208	4.06	🔴 −0.29	17.8%
Oxtail / coda alla vaccinara	61	4.05	🔴 −0.30	14.8%

Read the last column first. The share of one- and two-star reviews is the number that separates these dishes, and it ranges from zero to nearly one in five.

The trade-off: these are whole-meal ratings, not dish ratings. Someone who mentions cacio e pepe and gives two stars may be angry about the wait, the bill or the waiter. What the column measures is how often an evening that included this dish went badly — which is still the thing you are deciding about.

Cacio e Pepe Is the Riskiest of the Four Classics

The four Roman pastas are usually presented as a set. They do not behave like one:

Pasta	Reviews	Rating	vs baseline	Share of 1–2★	Verdict
Carbonara	773	4.38	+0.03	10.1%	🟢 safe
Amatriciana	155	4.32	−0.03	10.3%	🟢 safe
Gricia	68	4.12	−0.23	17.6%	🔴 risky
Cacio e pepe	208	4.06	−0.29	17.8%	🔴 riskiest

Carbonara is the most ordered dish in our corpus by a distance — 773 reviews name it — and it sits at the baseline. Amatriciana sits there too. Cacio e pepe and gricia both fall about a quarter of a star below, and both carry a one-or-two-star share around 17.5%, against 10% for the other two.

That is the reverse of the reputational order. Cacio e pepe is the connoisseur’s order, the three-ingredient dish that supposedly separates a real Roman kitchen from a tourist one. In our data it is the order most likely to end in a bad review.

Extremely peppery Cacio e Pepe, terribly overcoooked lamb chops. — Google Maps, 1 star, August 2026

We lined up for 30-40 mins to have a mid cacio e pepe, carbonara, and amatriciana. — Google Maps, 2 stars, September 2025

A plausible reason, which our data can suggest but not prove: cacio e pepe has three ingredients and no margin. Pecorino, pepper, pasta water. There is nothing in it to hide behind, and at a restaurant turning over hundreds of covers an evening, the sauce is the first thing to break.

What Goes Wrong Is Seasoning, Not Technique

We read the 110 one- and two-star reviews that name one of the four Roman pastas and sorted what they complain about:

Complaint	Reviews (of 110)	Share
🧂 Too salty	12	11%
😐 Bland, no flavor	11	10%
🍝 Pasta under- or overcooked	8	7%
🥣 Sauce texture — clumpy, watery, made with cream	5	5%
🌶️ Too much pepper	4	4%
🧊 Arrived cold	3	3%
🫗 Oily or greasy	3	3%

The top two complaints are opposites. Twelve reviews say the pasta was too salty. Eleven say it had no flavor at all. Together they account for a fifth of every bad review naming a Roman pasta — more than pasta doneness, sauce texture, temperature and greasiness combined.

Only five reviews describe the sauce itself failing — splitting, going grainy, or arriving as something it should not be:

The trade-off: seasoning is the failure you cannot inspect before ordering, and it is the one most likely to hit you. Nothing on the menu, in the room, or in the queue predicts it. That is the honest limit of any advice about what to order.

How to Order

Order carbonara if you want the safest famous dish. It is the most-ordered thing in our corpus and it sits exactly at the baseline. Its most common failure is salt.

Treat cacio e pepe as a bet on the kitchen, not on Rome. Nearly one in five reviews naming it comes with one or two stars.

Order tiramisu. At 457 mentions and 4.56, with 5.3% bad reviews, it is the single safest item we measured — and the only dish that clearly beats the baseline at scale.

Be careful with the offal classics. Oxtail sits lowest of everything with twenty or more mentions, and a third of its bad reviews mention the dish arriving cold.

Send back salt. It is the most common single complaint, it is fixable, and the reviews that mention it are the angriest in the set.

The trade-off: ordering for safety means ordering what most people order, which is how a kitchen ends up cooking one dish well and the rest to a schedule. If your reason for coming was the cacio e pepe, the numbers here are not a reason to skip it — they are a reason to pick where you eat it more carefully.

Methodology

Figures come from the TrastevereFoodTour research corpus: 26,181 items gathered between April 2010 and September 2026 from seven independent sources, of which 14,055 were processed for topic, sentiment and claims.

This article uses 5,020 rated reviews of three Trastevere restaurants verified by address and trading status in September 2026 — Tonnarello, Da Enzo al 29 and Nannarella. Of those, 1,535 name at least one dish.

Samples are deduplicated. The corpus stores a small number of reviews twice, once with a scraper-added prefix and once without, which an exact-text comparison does not catch; counting both copies would have inflated every figure here.

A review that names a dish is not a review of that dish. The star rating covers the whole evening. Every figure in this article measures how often a meal that included a given dish was rated badly — not how good the dish was. We know of no way to separate the two from review text, and we have not tried to.

Dishes are matched by name in English and Italian, including common misspellings of tiramisu and supplì. A dish is reported only when twenty or more reviews name it; saltimbocca, gelato, porchetta and maritozzo fall below that line in this sample and are not reported.

Complaint categories were assigned by keyword against the 110 one- and two-star reviews naming a Roman pasta, then the counts checked by reading. They are counts, not percentages of a large sample: twelve is twelve.

TripAdvisor figures use our unfiltered sample only. A second, deliberately negative sample was collected separately for failure analysis and is excluded from every average here.

Quoted reviews are reproduced verbatim, including the writer’s own spelling, from reviews written in English. Reviews the platform machine-translated are excluded from quotation, though they are counted in the averages.
