Subway has a brand of tea called Fuze tea. Until very recently, every time I had tried Fuze brand unsweetened tea it has been undrinkable. But it had probably been more than a year since drinking Fuze tea from any restaurant, so I decided to give it another try. This time it actually wasn’t too bad.  This is a freshly brewed tea, so I imagine the quality is largely dependent on who is brewing it.  If I have a few more experiences like the last one, I may be willing to give them a 3 out of 5 rather than 2.5.  The price varies, but is usually about $2-$2.50 for a large, and you are able to get your own refills.
