Average food, but good service. I had the spaghetti with red sauce, something I try to have the first time we visit a new Italian restaurant just for comparison. The sauce as a little thin and not very flavorful. I'm still learning the difference between "chain" Italian and family-run Italian restaurants, but so far I've been disappointed by the non-chain restaurants I've tried.
Del's portions were more than large enough to take home half for another meal, but for some reason the iced tea tasted like coffee. Del's, if you are going to reuse the brewer, at least clean it between brews.
My husband tried the eggplant Napoleon and was disappointed. The eggplant was overcooked and soft and there wasn't enough cheese. It was more of an eggplant "sandwich" than a Napoleon, but with almost no cheese.
Note added Nov 9: I think we've determined we don't like what passes for "good" Italian food in Pittsburgh because what we consider to be good Italian is almost exclusively Northern Italian and Tuscan food, not the more "central" Italian served in Pittsburgh. We'll still keep trying local restaurants, but at least we seemed to have found a pattern in what we dislike and what we like.
