The Photoshop below could be a little better. The problem with this is it's far too many colors. What restaurant would advertise in every spectrum of the color wheel? If you really were going to use this many colors, have the colors pertain to each food group. IE: repeating the greens purples and other such throughout this layout. Also, I see no real kerning to the font. Why script fonts? I can tell you, you wouldn't find a display like this in a restaurant in the states because the colors are too bright and it would make the text illegible to read from a distance. I would of have also chosen a picture for PS where the lights aren't reflecting in the shot. Also you repeat the "bag of chips a soda" basically in every panel. It's also the same one in every panel. Add some variety.
