Ronald Reagan Building & International Trade Center

It's not clear whether the small-government Republican would enjoy having one of the biggest, most expensive recent federal buildings ($768 million), filled with agencies like USAID and U.S. Customs, named in his honor. But it is an impressive sight inside and out (especially inside). The building has several restaurants fast-food and otherwise, public artworks, shops, and enormous conference and party space, popular for political galas, business conferences, and expensive wedding receptions. Free WiFi.
