They are not the menu but they do count for the drink. Any drink as long as it is not alcohol or a souviner cup. They are very good, very large and come in Vanilla, Chocolate and Strawberry. Not sure of the cost though. Just had one on the 11th.
I have eaten at Sci-Fi 3 times and new at Hollywood and Vine, Only Studio restaurant I have not eaten at. Food at Sci-Fi is good. Atmosphere is GREAT. My son's favorite.
