Although there are two locations, I've only used the one by the exit to Fremont St. On my last trip in May 2013, they would not give me a refill of brewed coffee purchased with my rewards card! This is unheard of! Wow! Was I flabbergasted! WTF???!!! All the barista lady would say is that they don't give refills. I've received refills before on previous trips, so if this is their latest attempt to squeeze more $$ out of me, I think I'll grab my java from somewhere else.
Turns out the store is most likely no longer a "participating store"...
From the Starbucks website: "My Starbucks Rewards members at Green and Gold levels are eligible for free refills on brewed or iced coffee or tea, regardless of the original beverage purchased, while they are in a participating StarbucksĀ® store."
