Hitman: Absolution HD (EP)

This can be completed on Mission 2 and beyond. An easy place to get this is on Mission 2: The King of Chinatown. Walk into the crowded area where the main target is. Walk to a stand with food on it (there is a sushi plate). Grab the menu and you will look at it and blend in. Since there are police and the main target around, the achievement should automatically unlock.
