I went back to Mosto tonight for dinner with a friend (it was my 2nd time there, her 1st).
The food was again quite good, and an excellent value. We shared insalata di frutti di mare which was fresh and very good. For my main dish, I got lasagne vegetale, which was great, really tasty. I couldn't isolate all the things that were in it, but one creative touch was fried, caramelized onions, of which there were copious amounts in the center. The lasagne was rich and full of ricotta cheese. My friend got a special, tagliatelle con agnolotti(?) e ragu. I forget the exact name, but the sauce was basically a high-quality ragu made with plenty of red wine, with pieces of lamb added. It was solidly good, better with pepper and cheese, but not special like the lasagne. My friend got a glass of Chianti which tasted like some of the good vino da tavola Chianti I used to drink in Siena.
My only complaint about this place is that it is too loud. The loudness bothers me before I get the food and after I'm finished eating it, and it's not conducive to conversation. But while I'm eating the fine food, I don't care about the loudness of the conversations over the repetitive music playing on the sound system; I just eat and enjoy.
The meal cost $45 for the two of us, including tip, and I think that's damned good for food of this quality.
