I'll probably be in the minority, but if you're looking for something different and are sick of all they icing-laden whitey cakes at Safeway and the like, you can try ordering a cake from T&T (the Asian supermarket). They have a moist pound cake with fruit inside and chocolate/light icing on the outside that's a nice alternative; they also have various other cakes (again with fruit -- the mango cake is pretty good).
If it's for a kids party, however, just go with the said whitey cakes and you should be fine
