L and I decided to give this a try for lunch. L had the pasta carbonara which she declared to be very good; it was clearly loaded with bacon. I chose the lasagna; it was very nice, cheesy without being too much cheese and the meat flavor came through. The red sauce was not overbearing. It was accompanied by a nondescript salad and uninteresting piece of foccacia.
L was warned off of the house white wine and had a nice chardonnay while I made the mistake of having the house red; it was virtually vinegar.
The service was very good. I would return, just avoid the house wine.
