Maintaining a historic facade doesn't preclude you from modernizing the insides, which is why the White House has an elevator, and a black guy. Creating a sleek burger paradise inside a historic McKinney building, Square Burger.
Square's helmed by a pair of Goodhues vets, one of whom diverted to SF and LA to sous chef at Myth & Spago before returning to help convert this 81-year-old art deco landmark's interior into a modern, gourmet-burger-and-more tap house with whitewashed walls, a bamboo-and-cork bar, and blue LED sconces set off by a wall of taps backed by recycled blue tile and glass (who doesn't like the high-lonesome glow of blueglass?). The Empire Bakery-bun'd burgers start with all-natural beef ground fresh daily by a butcher 1.5 blocks away, and get topped with everything from avocado & bacon to cacciotta cheese & prosciutto di parma; not-cow patties include smoked salmon and Colorado lamb (Colorado buffaloes refused to come to Texas, but they had no ground game anyway). Beyond the burgers there's everything from Franconia Dunkel-glazed ribs to pan-seared halibut, plus sides from "colossal" tempura onion rings to seasoned sweet-potato fries, a healthy alternative to getting regular fries with your colossal tempura onion rings.
As for booze, there're standard cocktails and a wine list that'll soon reach 60 bottles, but the 30 taps dominate; except for Guinness and Young's DCS, they're all choice North American picks, including four varieties of McKinney's own Franconia, plus Trois Pistoles, Deschutes Black Butte, Old Rasputin, and Rogue Dead Guy -- a historic feature the White House will be stuck with until they can grease Taft out of the tub.
