Find yourself a nice orange citrus tea. Those are pretty unique, and I've yet to have a bad one. You should probably round out your palette by trying at least one chamomile tea as well.
In my opinion, teas in the fruit-category tend to be nicest, chamomile is all the same, and both black and green come in an infinity of varieties, but teas from the same region have the same kind of taste, but with varying qualities.
White tea sucks.
