Well, heat, by itself, does not "Drain" the battery. However, high heat, and really cold temps will negatively effect a battery's performance.
You could have a rogue app. However, my guess of what happened is this....
-In a restaurant kitchen, there is a LOT of metal around you. This act's like a psudo-faraday cage, blocking a lot of the cell signal.
-Also, there is a lot of EMF (ElectroMagnetic Field) interference from the appliances, lights, microwaves, compressors on the coolers/freezers... These play "Merry Ha Ha" with your radio signal.
-Put those together, and the phone has to put more power to the radio to maintain signal. This will drain the battery MUCH faster. This also makes the phone heat up.
-The heat built up since the phone was in your pocket. This reduced the battery's performance.
So, your battery was not only drained from the extra power load put on it by the radio, it drained even faster due to the heat that built up in your pocket.
