Yay, drive through coffee!! This is a super cute place with friendly staff. I've never encountered them being closed without notice, but funny thing I do, I tend to frequent businesses during their normal hours of operation. You can find these hours easily by Googling their name and looking at their Facebook page. They have never been open Sundays and that is clearly posted on their Facebook page. I don't understand posting a negative review of a business because you were having a "throw caution to the wind" kind of day and not at least calling/Googling to find out if a place was open.
I'm personally thrilled they are there and love the convenience of the drive through. Besides Mountain Mojo there are approximately zero options in Fairview to do this unless you count Sonic, which I do not.
They have a nice selection of pastries and snacks, but I have only tried their bagels, which come toasted and smothered in cream cheese. I'm not a muffin person but their strawberry muffin was super moist/yummy. They have lots of coffee drink options, although I usually just stick to regular coffee but I am glad that they offer some healthier coffee add ins (skim/soy milk, stevia instead of Splenda, etc.)
Oh and their open/close sign is adorable. Another clear indication of them being open/closed. ;-)
