If you’re ever in downtown Milwaukee, the spy-themed restaurant The Safe House is not to be missed. Your first assignment will be to simply find it—there’s no sign or marquis, just simple red door by a plaque labeled International Exports LTD. Once you enter, be ready with the code words (the website is helpful). This place is great fun, and while your meal is being prepared you can undertake a scavenger hunt in what is basically an espionage-themed museum. Secret passages and a back door alley exit are all on the menu. Enjoy!
