Certain exemplary embodiments relate to techniques for generating electronic menu (eMenu) graphical user interface layouts for use in connection with electronic devices (e.g., tablets, phablets, smart phones, etc.). A virtual grid-based layout including rows and columns that together constitute regularly sized and shaped grid cells is defined. Input identifying items to be included in the eMenu is received. Each item has associated length and width dimensions corresponding to a number of grid cells. At least some of the items are flagged for inclusion in the eMenu. Those items marked for inclusion are automatically and programmatically arranged in the eMenu in the grid cells of the grid-based layout in a manner that minimizes the number of unused grid cells. A tag-based representation of the layout corresponding to the formatted eMenu is stored. The file is made available to the electronic device in enabling the formatted eMenu to be displayed thereon.
