Are there any H-Town coffee shops that I can get a cup bigger than 16oz, other than Starbucks?

Seriously, I don't want to support Starbucks anymore, but it's the only place where I can get a cup of (drip) coffee to go, that's bigger than 16oz. I don't know of any local businesses inside the loop that have a 'comprable' Venti / 20oz cup. Sup with that..?!
