From February 17 through March 31 2011, Atlus and Collabo Dining collaborated to promote Catherine. The Collabo Dining in Tokyo's Aoyama area sold an original menu consisting of cocktails themed around the Catherine characters and a "Stray Sheep" brand pizza (named after the bar that appears in the game). Those who bought the items received a coaster themed around the game.
The drinks for the various characters consist of the following:
White Rum, Cola, Cut Lime. Made in the motif of the Rum and Coke Vincent drinks in the game.
Framboise, Peach, Grenadin. The framboise is apparently meant to represent deep regret and affection.
Black Sambuca, Milk, Cream. The black sambuca was used because the game's developers asked for a dark colored cocktail.
Beer, Soda, Melon, Yogurt, Cucumber. The development team requested the cucumber apparently because it has something to do with the game.
Nihonshu, Lemon, Tonic
Grapefruit, Tonic, Cherry
Mango, Orange, Cherry. Both Erica and Tobias' drinks have two cherries.
Gin, Vermut, Black Olive
Champagne, Amaretto, Cherry. The cherry is meant to be in the image of the character's red afro.
Yogurt and Milk. Designed in the image of a sheep. This is a dessert cocktail.
The Stray Sheep pizza is a 16 inch margherita with salami topping. The drinks run ¥850 each. The pizza is ¥2,500.
Atlus also says that it's possible a collaboration cake will be added to the menu between the end of February and early March.
