All over town, hotel restaurants are turning over. Seasons at the Four Seasons closed this week and will be reborn as something else next summer. Silks at the Mandarin Oriental closed earlier this year and was replaced by Brasserie S&P. Parallel 37 replaced the Dining Room at the Ritz last December. And now, Grandviews on the top floor of the Grand Hyatt at Union Square is closed as well, and tonight marks the opening of One Up, the new bar and restaurant that's one level up from the lobby, on a previously under-used mezzanine of the hotel.

Grandviews was, in the words of SFist's Brock Keeling, "the worst/best place in S.F." You probably went with your mother/aunt/uncle once. The drinks were terrible. The food was worse. But hey, everything changes! In addition to the lobby and restaurant makeover, the hotel is in the process of redoing all the rooms too.

One Up will boast a fresh and unique bar program from bar star Scott Beattie (formerly of Cyrus, and Plum Bar in Oakland), and a new food menu from chef Ian Libberton, featuring more seasonal, California dishes with farms listed in the names, like Marin Sun Farms lamb Bourguignon with pappardelle, hedgehog mushrooms, parsnips, and lemon-mint pistou.

Below, a video rendering of the new space, in the absence of any advance photos. Note the lounge with all the rock-and-roll photos on the walls, paying homage to S.F.'s place in rock history.
