> Ice cold, almost room temperature or somewhere in between?

Just slightly cooler than myself.

In fact no food should be 'ice cold', even ice cream. For example beer is often served way too cold and therefore taste like mineral water. There is of course beers that taste like mineral water in any temperature, bud i will not tell which ones. ;-)

Flavor is partly taste (bitter, salt, sweet, sour, umami) and partly smell (the rest), mostly smell. If food is too cold small molecules that create flavor will not evaporate in mouth (or before) and will not reach smell receptors in your nose before you swallow the food. This is why food is tastless if you have cold.
