We went for lunch at The Safe House, a restaurant for spies in Milwaukee. You enter the restaurant through an unmarked door in a back alley which leads you in to a tiny room.

You then punch yourself in and a secret door opens in a bookcase.

You then walk through a long tunnel and another wall opens where you're met by a hostess who shows you to your table.

I ordered the 'we better stop meeting like this' veggie burger.

After dinner we explored the rest of the restaurant. It was gigantic with tunnels, hidden rooms and fun things to find everywhere.
