Porto Fluviale means River port, but it looks nothing like. It is big though, and often crowded, and if a hoard of hungry locals believe it's a good option, then you're in for a treat.
But you also might experience a long wait to be served or to even see the food you ordered. Partly it's the price to pay for a popular destination, partly they might have overshot the sizing, since the place is massive. When you reserve you're faced with the option between pizzeria and trattoria. And while you try to avoid a classic "I made a huge mistake" moment, the explanation you're offered is a bit vague, so you really only learn in hindsight: pizzeria has pizza, fried deliciousness and grilled meat. Trattoria has pasta options and different meat offerings. Either way, the menu is interesting, diverse enough for any group and very reasonably priced. The T-bone steak is a massive slab of meat, which for €20 is a steal. I enjoyed the "Chicken tagliata", mostly dark meat, nicely seasoned and sitting on a bed of salad. When in Rome, cicoria and indivia sides are almost obligatory additions to any meat dish. If pizza is your thing, you'll love the place and the selection, all in the thin local version (not the fluffy crust version from Naples). To get the best of both worlds, get a focaccia as a side, a mix fried platter for starters and meat for a main dish.
If you can, come by for brunch over the weekend. The buffet is amazing, I don't usually gush over buffets but this one will have you coming back for more, considering to restart from pasta once you've tried the desserts. Perfect option for vegetarians as well.
Four stars just because service can be painful at times, which makes the self-service brunch a much more relaxing experience.
Choose the time of the day wisely to avoid crowds, possibly reserve in advance and just arm yourself with patience to find a parking spot. Life gets much better afterwards.
