Mosaics Community Café in the Chicago area operated on a model that was, by the standards of the restaurant industry, radical in its simplicity: there were no prices on the menu. Diners paid what they could afford, what they felt the meal was worth, or nothing at all if circumstances required it.

The model, sometimes called "pay what you can" or "community café" dining, had predecessors in various cities and was part of a broader movement exploring how food service could function as a vehicle for community rather than purely as commerce. The idea was that a single dining room could serve people of very different economic means, with those who could pay more effectively subsidizing those who could not, and with the dignity of all diners preserved by the absence of a two-tier system.

The practical operation required the café to identify a rough break-even point and trust that sufficient customers would pay at or above that level to cover those who could not. This trust was not unfounded — most operations of this kind found that a significant proportion of diners paid more than a conventional market price, motivated by understanding and appreciation for what the café was doing.

The food insecurity problem in communities like those Mosaics served was not, of course, solvable by a single café. But the model did something beyond feeding hungry people: it preserved the social ritual of a shared meal, the experience of sitting in a comfortable space and eating food prepared by others, that soup kitchens and food pantries, however necessary, could not provide in the same way.

Hunger is a material problem. Dignity is also a material problem. Mosaics addressed both.
