We tried Andiamo based on a recommendation from the clerk at our hotel. It turned out to be a good find.
The interior is tastefully done with subdued (but not too dim) lighting, white tablecloths, and a large fireplace. Service was very good -- the wait staff didn't hover over you, but somehow arrived at just the right moment to whisk away a finished plate or refill your water glass.
I had the lamb chops and the Tuscan potatoes. I'd ordered the chops medium rare and at first was concerned they were underdone as they were *very* red on the outside, but once I cut into them the interior was done perfectly. The Tuscan potatoes were probably slightly underdone (a bit stiff) but the flavor was wonderful. My wife had the wedge salad (which she raved about) and the agnolotti, which she was very happy with. Our daughter had the gnocchi which she was happy with as well.
One minor annoyance was that they had the front (large) parking lot roped off for valet parking only, and the small rear lot was already packed full so there was no choice but to use the valet. In this case the valet wasn't really providing any kind of useful service, as there were plenty of spaces close to the building and he was only saving you maybe 30 feet of walking. Fortunately there was no valet charge, just tipping the attendent, but it seemed silly.
