In the 2010s, American cocktail bars were obsessed with the Prohibition-era aesthetic. All those suspenders and vests. Lots of ice blocks being clubbed with big wooden mallets. Handlebar mustaches. Rough Rider, which opened this summer in the basement of the Ten-O-One building, has a whiff of that vibe, but it draws its inspiration from even farther back in time. It's named after the Rough Riders, the ragtag cavalry of cowboys Teddy Roosevelt led during the Spanish-American War in the late 19th century. Cocktail-wise, the menu's split into four sections, two of which are very old-timey: cobblers (which include jam) and punch (made with tea). The place is properly dim and does a nice job evoking Teddy's era, with caskets jutting out of the walls, built-in bookshelves, ornate woodwork (including in the elevator), and a lovely white marble bar top. (The team behind Rough Rider also is involved in The Whining Pig and Pigtails Downtown.) The place looks built to last, like much of the stuff produced in this proud American era. Here's hoping the bar is, too.
