I was just in Rome last week, and decided to ignore the mixed reviews Sora Lella has been getting. In error, I discovered, for it was undoubtedly the worst restaurant experience of the trip.
We got to the restaurant at around 8:30 and had to ring a bell for entry. I didn't think anything of it then, but I now see is as symbolic of the general unpleasantness of dining there. There were only a few other diners present throughout our entire meal, and everyone was either silent or speaking in whispers. This was probably inspired by the extremely unfriendly staff, who made us feel quite unwelcome from the beginning, when they ushered us in without even a greeting, and refused to speak to us in Italian for the rest of the evening.
They brought us a complimentary antipasto, which was two layers of horrible bland bean paste and some gelatinous tomato-ish thing, served in a mould. For our primi, we ordered a fresh pasta with pork cheek and pasta with sausage. Both of the pastas had a rubbery texture and the sauces were so oversalted that you couldn't taste the meat. We split a secondo, which was perhaps, the most awful tasting lamb I've ever had in my life: greasy, burnt in some places, and wrapped in a foul tasting pancetta. We also had a bizarre contorno (I don't remember what was in it), but it was drenched in olive oil and had the consistency of seaweed.
They kept us waiting for the bill for about 45 minutes, even though there was barely anyone else in the restaurant. The bill came to about 90 euros for the meal described above, and we left feeling extremely ripped off.
