Via Napoli's prosciutto and melon pizza is legit. It's extremely expensive of course, but it's excellent. I'm convinced they found a way to add extra gluten to the dough. It's the only way I can explain crust that soft and chewy.
BOG breakfast is consistently awful IMO. I tried Space 220 and the experience was fun once, but I won't be back as long as it remains prix fixe. My steak (ordered medium rare) was straight-up raw and didn't seem to have any salt on it. I'm always disappointed by the Ohana steak, and there's no justifying the price, but the shrimp are so good that I still make a reservation there very time.
This past trip we had great meals at Boma (always), Tusker House (new for us, but great diverse offerings around brunch time), Liberty Tree Taven (hit or miss, but this time was great).
