The coffee is great and so is the space inside the coffee shop with a considerable amount of tables. The main things I dislike about the coffee shop are the extremely rude staff and their very odd and inconsistent pricing. On one occasion an older gentleman tries to go to the restroom but goes through the wrong door. The apparently very peeved female cashier proceeds to yell at him because he went through the wrong door. There was no reason to yell at the man and found it extremely rude for such a small oversight. On another occasion I ordered a frozen mocha and they charged me $5.60. I then later returned and purchased another mocha and was charged $4.30. I didn't have cash and there is a $5 minimum for cards so I asked if it was the same drink due to the difference in pricing. The female cashier then spoke to her manager and she came back and charged me $5.60. I don't understand how they make up their pricing but it certainly did not seem right. My friend also told me they charge a "service fee" which he nor I have ever heard of any coffee shop charging.
