who sells green tea by the gallon?

I need some green tea recs.  I've tried so many times to brew my own at home and it's gross.  I can't make it work and I have to choke it down. And I'm a huge fan of iced tea.

I'm all up for going to restaurants and getting some by the gallon.  Know anyone that sells it?  Anyone know if the passion tea at Cheesecake Factory is green tea? Because I could drink my weight in it.  TIA!
