Tonight, West Hollywood (or those connected enough to score reservations, anyway) gets its first look at SBE’s supper club, Foxtail (pictured). Preview crowds were dazzled by the trilevel restaurant’s design, which SBE partner Brent Bolthouse describes as “ ‘70s chic meets ‘20s Art Nouveau.” Conceived by Franklin Studios, makers of Santa Monica’s Tengu, Foxtail (9077 Santa Monica Blvd.) exudes studied, timeless and decidedly “adult” cool with custom-built leather seats and opulent European-style design. A-list actors and the agents who love them (including Endeavor’s Patrick Whitesell, one of Foxtail’s four high-profile entertainment biz investors) will no doubt be spending lots of busy nights talking shop inside Foxtail’s second-floor hideaway, an ultra-exclusive private lounge with its own separate entrance. Above that is a smoking area featuring stunning greenish copper-patina wallpaper and relief-like hanging brass sculptures. The ground-floor restaurant is open for dinner; the rest will debut in mid-to-late March, says Bolthouse. . . . Cold, rainy weather couldn’t keep the Oscar glitterati (and a small army of British expats) from checking out the Los Angeles reopening of Soho House last week. The famed London-based chain of exclusive clubs showed the Sunset Strip a thing or two about a classy-yet-hip affair from their newest temporary location in the 14th-floor penthouse atop Luckman Plaza (9200 W. Sunset Blvd.). Raw, exposed ceilings (with pink fiberglass insulation showing) and cozy seating arrangements somehow clash perfectly at the space. Mark Somen, the club’s North American director of operations, tells Night Lines that Soho House is “in active negotiations” to make Luckman “the permanent home of Soho House” in L.A. by 2009.
