Staff messed up my drink, then instead of remaking it they ignored me for 5 min then handed me the same drink. Either that or they remade it in the same cup (handwritten note on side for wrong drink), which is a healthcode violation. Also told my Mom that hers was decaf but it wasn't. We know because she is allergic to it and she had a reaction 5 minutes into her drink. Serious staff and quality control issues. Which is too bad because my Mom said the coffee was quite tasty before she had to stop drinking it. I tossed mine, might have had spit in it.
