I frequented this coffee shop for about a month.
I had heard negative things about the owner/manager's attitude from others, but I like to give people a chance myself. After being glared at, talked to rudely, and ignored on several occasions, he finally was SO rude to a friend and I that we are never going back there (and neither are any of my other friends).
If you don't mind being treated like THEY are doing YOU a favor by deigning to serve you, then this place might be fine for you.
