Burgermania

From BoardGameGeek:

Burgermania is a real-time dexterity game. Two players are racing to build hamburgers based on their order cards. The conveyor belt is battery-operated, and players try to stack ingredients like lettuce, cheese, and tomato on their hamburgers using tweezers. At the end of the conveyor line, the hamburger is placed on a plate. The conveyor belt gradually accelerates during play, so later hamburgers become more difficult to assemble.
