That was a big oops for Puccini to put the Castle photo on the site. I agree it looks a bit bland, but that was likely the design brief, and Puccini does a LOT of corporate "look" restaurants, and they do them very well. They're one of the design groups of choice of the moment for hotel, theme park and upscale chain management firms. If you've been in a Kimpton, Hilton, Starwood, Fairmont, Hyatt or any new restaurant in Orange County, CA lately, there's a decent chance Puccini had a hand in it or bid on it. They also did F&B for Aulani. They're good at designing for high turnover. (Orange County restaurants are odd - they all have a design feel that says OC. Elements from the design then seem to creep out to the rest of the country over time.) For those afraid of being on top of the next table at the long row banquette, I expect those tables will be spaced farther than they look in the concept. I wish they had gone a bit "more" but will wait and see. I think it will feel better in person than it looks, even if I wish it were more future-retro or incorporated more themed and less any-restaurant.
RE: the menu and molecular gastronomy, it's difficult to do molecular on the scale that the CG does in covers, let alone maintain quality. Plus it's still pretty foreign to Joe Everybody, and although California Grill is one of a few restaurants on property that does a great job introducing diners to new things, that might be a bit too out-of-the-box. I would love to see some molecular cocktails at the bar, though.
