I've only been to Grano Arso twice, but both times it was amazing for me. But maybe I'll change my mind! I didn't really think about the cost since I expensed it both times
I do think there's something about living right next to something that makes it slowly seem less special. Bufalina is basically my neighbor and the charm has gradually worn on me a bit...
I haven't yet, but my brother and mother both have separately on several occasions now, and my wife had drinks and apps there. Everyone said it was "great", but I don't really trust any of them. So I'll withhold judgement until I get there myself. Amarone's on the green in Guilford is also pretty good, not amazing but very solid if you need a spot for dinner in the area.
