Started going in here during the summer. My girlfriend stopped in there for a quick coffee by chance a few days before hand and spotted a drink on the menu that had peanut butter, banana, maple syrup, soy milk, a sprinkle of cinnamon, a shot of espresso, all blended up with ice. I really fancied a drink like that for quite a while.
I had something similar from Kupfert & Kim that was absolutely dismal, which took three people to make and another five looking at them do it while there was about another five standing around the corner chatting away. It was terrible, I waited I don't know how long for that many people to make an expensive tasteless cup of over hyped dribble.
While in Rick's (This drink is called 'The Doug,' here.) it took a few minutes to make, by one person and it was amazing. So good in fact, I go there a few times a week to get this ever since. Every time I go in it's a pleasant experience. Great, friendly staff who know how to do their jobs and like doing their jobs, great atmosphere and ambiance. If I don't go there at least once a week, I get withdrawal.
Just go there and treat yourself to a Doug and a peanut butter brownie. You'll feel like you have just achieved a life goal you never knew you had afterwards.
