Meh is the perfect descriptor for Porta Alba. We went with a group of friends, of whom 2-3 had been at the old location. I have no complaints about the decor, and really none about service. Neither stood out for good or bad reasons.
The food...yeah, meh. The pizza was okay. (And yes, I am aware this isn't supposed to be American pizza. I've tried pizza all over the globe and like each variation for its own reasons.) Even my husband, who will pretty much eat anything and at least say it was okay, was pretty meh about it. I had a special pasta dish. Just based on that, I would give a 3-3.5 however because it's not a normal option and what I tried of my dining companions' food was also meh, it's not enough to raise the overall score.
Upon leaving the restaurant, my husband and I immediately named this a we-won't-pick-this-restaurant-again-but-won't-throw-a-huge-fit-if-a-group-of-friends-want-to-go place. Thankfully, we haven't had to go back.
