A little bit disappointed. Never once met a grouch at Grouchy John's;)
Seriously though, had lived a block away from this place for about 2 years and never came here even once until a few months ago. Always drove by and figured it was just another boring coffee shop.
It is everything but "just another" or "boring."
I fell in love with this place, now I stop by for a caffeinated treat as often as possible.
I don't want to spoil it for you, so that's all I am going to say. If you live nearby, or pass it on your commute, stop in and see for yourself.
Strongly recommend going inside, at least for your first visit. Check out the interior, but more importantly study the menu and find your happy drink :)
