I was told that I *had* to come here. I was in the neighborhood and my time in Rome was winding up. I'd had some incredible porchetta in Florence but I hadn't had any in Rome. I was told I *had* to correct this. So, I broke up my Colosseum/Roman Forum day to make time to come to Er Buchetto and see what was up. Spoiler: you don't *have* to come here. The meat is good enough but I wouldn't re-arrange your day for it. I enjoyed my sandwich in Florence much more.
This shop is small -- even by European standards. Getting in and grabbing a table/service is ruthless. You have to go in with full confidence and no regard for those around you. It's like jumping in to a really intense double dutch session. I was cut in line twice so I just decided to be extra aggressive and take a seat. I hate being that way and the stress of the situation, undoubtedly, colored my reaction/experience.
There's not much to it: communal (sort of) seating, porchetta sandwiches and wine. I sat, pantomimed what I wanted (a sandwich and some vino), watched the owner slice some meat of the spit, put it between bread and give it to me. His son (?) poured some tap wine and I went to town. The sandwich was a bit dry but it still had a decent taste. It was also much larger than I expected. In fact, my sandwich and wine ran me 4.5 euros. For the area, that was a steal. Perhaps had I stumbled in to the shop without any knowledge of it or expectation for what was to come, I would have enjoyed it more. Perhaps if I didn't have to push and shove for a seat, I would have been in a better mood. Alas, neither happened and I had the experience I had. YMMV but I don't think it will. It's good but you won't slap your mama for it. For the effort involved, though, you might want to slap yourself.
