1. A multi-zone food holding bin comprising: a chassis having a front face and an opposing rear face;a first food holding compartment within the chassis, the first food holding compartment having at least a first opening, the first opening being open, uncovered and located at the front face of the chassis, the first opening being configured to allow food items to be placed into and removed from the first food holding compartment;a continuous and planar surface forming a bottom of the first food holding compartment, the continuous and planar surface extending completely to the front face of the chassis, the continuous and planar surface comprising Aluminum;a first food holding zone formed in the first food holding compartment, the first food holding zone having an independently controllable radiant first heating element disposed at a top portion of the first food holding compartment, and an independently controllable conductive second heating element disposed at a bottom portion of the first food holding compartment;a second food holding zone formed in the first food holding compartment, the second food holding zone having an independently controllable radiant third heating element disposed at the top portion of the first food holding compartment and an independently controllable conductive fourth heating element disposed at the bottom portion of the first food holding compartment; anda food holding tray disposed in the first food holding compartment, the food holding tray resting on the continuous and planar surface,wherein the first food holding zone and the second food holding zone are adjacent one another across the continuous planar surface and the first food holding zone is configured to maintain a first temperature and the second food holding zone is configured to maintain a second temperature, the first temperature and the second temperature capable of being different than one another, andwherein the first independently controllable heating element heats the food holding tray radiantly from above and the second independently controllable heating element heats the food holding tray conductively from below. 2. The food holding bin of claim 1, further comprising: a second food holding compartment disposed below the first food holding compartment within the chassis, the second food holding compartment having at least a first opening, the first opening being open, uncovered and located at the front face of the chassis, the first opening being configured to allow food items to be placed into and removed from the food holding compartment; anda shelf located between the first and second food holding compartments, the shelf comprising a first side and a second side, the first side facing into the first food holding compartment, the second side facing into the second food holding compartment, the second and fourth heating elements being disposed in the shelf and in thermal communication with the first side, the second and fourth heating elements being capable of providing different amounts of heat energy into the first and second food holding zones of the first food holding compartment; anda controller operatively coupled to the second heating element and to the fourth heating element, the controller being configured to independently operate the second heating element and the fourth heating element. 3. The food holding bin of claim 1, wherein the first and second food holding compartments each have a second opening, uncovered and located at the rear face of the chassis. 4. The food holding bin of claim 1, wherein the first heating element is adapted to output more heat energy than the second heating element. 5. The food handling bin of claim 1, further comprising a lid located in a top portion of the first food holding compartment, the lid capable of being inserted into a shelf above the continuous and planar bottom surface. 6. The food holding bin of claim 5, further comprising a latch located adjacent to the shelf, the latch having a body including an open center portion, the latch being rotatable or translatable relative to the shelf between a locked position and an unlocked position. 7. The food holding bin of claim 1, further comprising a lid on the food holding tray. 8. The food holding bin of claim 1, wherein at least one of the first heating element and the second heating element is an electrically resistive heating wire. 9. A method of maintaining different temperatures in a food holding compartment of a food holding bin, the method comprising: providing a food holding compartment with a first food holding zone and a second food holding zone adjacent to one another, the first and second food holding zones sharing an uninterrupted continuous planar bottom surface comprising Aluminum, the uninterrupted continuous planar bottom surface extending to a front face of a chassis forming the food holding compartment, and a food holding tray disposed in the food holding compartment, the food holding tray resting on the uninterrupted continuous planar bottom surface, the first food holding zone including a first independently controllable radiant heating element that heats radiantly from above and also includes a second independently controllable conductive heating element that heats conductively from below, and the second food holding zone includes a third independently controllable radiant heating element that heats radiantly from above and also includes a fourth independently controllable conductive heating element that heats conductively from below;independently setting a first temperature in the first food holding zone by operating the first independently controllable heating element and by operating the second independently controllable heating element; andindependently setting a second temperature in the second food holding zone by operating the third independently controllable heating element and by operating the fourth independently controllable heating element,wherein the first temperature is different from the second temperature. 10. The method of claim 9, further comprising providing more heat energy from the first heating element than from the second heating element.
