A burger, chips and fries scene created using blender 2.73. It has a high poly count but subdivisional modifiers are applied on almost all objects and you can easily decrease the levels to get low poly count. All textures are made using procedural textures and displacement modifiers are used where necessary, eg cutlet.
What you see is what you get.
--> Burger - A burger with seeds on top, cutlet and a cheese slice. The seeds were basically made using blender's particle system so everything is pretty accurate.
--> Chips - Simple chips with subdivisional surface modifiers applied.
--> Fries - Fries with subsurf applied as well.
--> Ketchup - Tomato ketchup made using fluid simulation in blender.
-->Simple plate -- A very simple plate just for showcase purposes.
-->Simple table -- A simple table with procedural textures and a glass surface
