Oh, a tea latte is basically like a coffee latte only it's made with tea instead. A lot of places do a chai tea latte but there are more and more that will do it with other teas as well. they basically just brew the tea in a small amount of hot water and then add steamed milk and sometimes vanilla flavoring. I usually sweeten it a bit after (I taste it first because some places sweeten it for you). They're really yummy.
