    Ordered the Rasberry Rockstar mixed drink for my caffeine hit in the morning when I got there I was told they ran out of Rockstar and instead of asking if I wanted a different drink to get my energy for the day they made it with soda water told me about it and closed the window. Guess I don't get caffeine today.

    Don’t come here if you want burnt coffee. They somehow always burn their coffee and it tastes terrible. Maybe the crew needs retraining.
