Mike Chen is packing it in. "It's a mess," he says of Standard Restaurant's dining room. After backing chef Tim Byres to bring the former Deep Ellum restaurant to Uptown early last year, Chen closed the restaurant several days ago after dining room sales tumbled some 50 percent in recent months. This is the second concept fizzle (the first was Stolik) for Chen in this former Martini Ranch spot, and he's in no mood to try again. He blames Standard's demise on a neighborhood/concept mismatch. "Not too many people were crazy about the food," he deadpans...It doesn't seem like a name to tickle the easily intimidated. Nevertheless Sigel's new concept will most likely be stamped Sigel's Elite. "We want to try and bring the Sigel's experience up a notch," says the liquor retailer's John Rector. Sigel's Elite will start with two locations: a 4,000-square-foot unit in The Shops at Legacy (Phase 2) set to open before Thanksgiving, and a 14,000-square-foot footprint at Fitzhugh and Cole in the former CityHomes sales center set to hit before Christmas. The stores will feature dedicated classroom space (watch out, Tony's), an aggressive tasting program, specialty cheeses and maybe prime beef, with the Dallas version featuring a rare spirits room.
