Add this to the long list of disappointing restaurants in the Church-Wellesley area.
A caprese salad made with underripe supermarket tomatoes basically serves as a metaphor for the whole experience. It's the height of the season for beautiful, local tomatoes, and the whole point of a caprese salad is to highlight their flavor. But the cooks at Osteria apparently do not care, and the server seemed confused when I tried to explain my disappointment.
I followed the salad with a spaghetti amatriciana. The pasta was nice and perfectly cooked, but it was drowned in an excess of sauce that tasted like a doctored can of Hunt's.
Not to my taste, and I won't be back.
