Wendy's and White Castle are also headquartered in Columbus. Major foreign corporations operating or with divisions in the city include Germany-based Siemens and Roxane Laboratories, Finland-based Vaisala, Tomasco Mulciber Inc., A Y Manufacturing, as well as Switzerland-based ABB Group and Mettler Toledo. North Market, a public market and food hall, is located downtown near the Short North. It is the only remaining public market of Columbus's original four marketplaces. Ten restaurant chains are based in the Columbus area: Charley's Grilled Subs, Steak Escape, White Castle, Cameron Mitchell Restaurants, Bob Evans Restaurants, Max & Erma's, Damon's Grill, Donatos Pizza and Wendy's. Wendy's, a Fortune 500 company, operated its first store downtown as both a museum and a restaurant until March 2007 when the establishment was closed due to low revenue. The company is presently headquartered outside the city in nearby Dublin. Budweiser has a major brewery located on the north side just south of I-270 and Worthington. Columbus is also home to many local-based micro breweries and pubs. Asian frozen food manufacturer and ex-destination tiki restaurant Kahiki Foods is located on the East side of Columbus. Wasserstrom Company, a major supplier of equipment and supplies for restaurants, is located on the north side. Lancaster Colony Corporation, a manufacturer of candles and Marzetti food products, is headquartered in the city. Columbus has many notable buildings, including the Ohio Statehouse, the Ohio Judicial Center, and Greater Columbus Convention Center, Rhodes State Office Tower, LeVeque Tower, and One Nationwide Plaza. Construction of the Ohio Statehouse began in 1839 on a plot of land donated by four prominent Columbus landowners. This plot formed Capitol Square, which was not part of the city's original layout. Built of Columbus limestone from the Marble Cliff Quarry Co., the Statehouse stands on foundations deep, laid by prison labor gangs rumored to have been composed largely of masons jailed for minor infractions. It features a central recessed porch with a colonnade of a forthright and primitive Greek Doric mode. A broad and low central pediment supports the windowed astylar drum under an invisibly low saucer dome that lights the interior rotunda. There are several artworks within and outside the building, including the "William McKinley Monument" dedicated in 1907. Unlike many U.S. state capitol buildings, the Ohio State Capitol owes little to the architecture of the national Capitol.
