Form Skybar soars sixteen floors above downtown St. Louis in the Hotel Saint Louis.

It may be positively frigid outside, but your new summer hangout is open for drinks and dinner as of today.Soaring sixteen floors above downtown St. Louis,is located on the original rooftop of the Louis Sullivan-designed building, which is now the Hotel Saint Louis. The room is glassed in on three sides, with one of those sides able to retract fully in nicer weather — and that means a view not only of downtown, the riverfront and Busch Stadium, but also of the hotel pool.The 2,480-square-foot bar hopes to be more than just a place for cocktails and a view. Its chef is Matthew Birkenmeier, and he made his name at the late, much-lamented Quincy Street Bistro.In a press release, the owners promise a menu that pays tribute to the city's past and present alike, with "Mississippi Crawfish Nachos in a Can," "Cherokee Street Tacos," made with short rib, and "Famous-Barr’s John White Burger." A pork trio offers pork steak, pulled pork and rib sliders, while you can also get Bosnian-style flatbread with Ajvar dip. In addition to a number of vegetarian offerings, they're serving "Impossible Sloppy Joes," a sloppy slider-style riff on the meat-free burgers.Form Skybar will be open 4 p.m. to midnight Sunday through Thursday and 4 p.m. to 2 a.m. Friday and Saturday. It joins Union 30 within the Hotel Saint Louis project , a $68 million renovation led by Amy and Amrit Gill of Restoration St. Louis and now operating as an Autograph collection Hotels by Marriott.
