I hear some christian coffeehouses can be good but something overtly in my face would be aggravating. Perhaps it's better that they define who they are.
I suspect that this place wasn't being "watched" and it strayed from it's intent. The coffeehouses that I've been to had a cover charge with standup comics and local Christian bands and all the coffee and donuts you could eat. There was always a Pastor or church Elder there. There was no mistaking what it was and the Pastor or Elder welcomed everyone but the conversation was just that, general, unless they were asked.
