An aid for dining in stand-up and similar situations where a person may simultaneously support a plate and a beverage container by a single hand. The invention comprises a universal food holding receptacle that is stably mountable on upright beverage containers of widely diverse shapes and sizes. The user holds a lower portion of the beverage container in one hand and uses the other hand for other activities such as taking food items from the food holding receptacle that is supported on the beverage container. The food holding receptacle is stably mounted on the beverage container in loose-fitting relationship so that the receptacle can be repeatedly mounted on and demounted from the beverage container in a facile manner while dining. The same food holding receptacle may also be used, after turning upside-down, to stably support beverage containers of diverse shapes and sizes.
