I recently had a very nice meal at this friendly and comfortable place on Ripa di Porta Ticinese, in the Navigli area. The place is recommended by the Slow Food guide to the Osterie D'Italia, and it deserves the recommendation.
I started with the "small" plate of salumi. Served on a wood board, it included several salamis and prosciuttos, coppa, bresaola, and lardo. There was also a really impressive range of cheeses of all kinds from all over Italy, and a spectacular looking tasting platter. As I was eating alone, I didn't try it. I did, however, ask for a piece of the pecorino di fossa along with my salumi. This was really superb.
I chose papardelle with a ragu of duck and chestnuts for my primo. Though it sounded wonderful, it was rather disappointing. The handmade papardelle were very nicely done, but the sauce was rather bland.
The secondo redeemed the pasta. It was a lovely filet, cooked just as I like it (very rare) with fagioli, rosemary, roasted garlic, coarse sea salt, and strips of very flavorful bacon. It was perhaps a bit salty, but I still thought it superb.
The wine list was very good, varied, and quite reasonable, with at least a dozen half bottles. I opted for one of these - the "Donnaluna" aglianico from Paestum by De Conciliis. Very nice and a good value at 13 euros. (The total tab for the meal was about 50 euros)
The staff and the other patrons were very friendly. Though dining alone in a smallish place packed with office Christmas parties, I felt quite comfortable. I would certainly return.
[On a prior trip to Milan in August, I dined at Al Pont de Ferr, another osteria on the same street, also recommeded by the Slow Food Guide. I liked it very much as well, though I can't remember what I ate. If Le Vigne is closed, it would be a fine alternative].
