I have been here few times by now mainly for coffee, donuts and gift cards. I have had good experience with coffee and donuts however I was surprised to experience that they don't keep gift cards handy. I came here to get set of 10 gift cards and they only had 2. I was told they get more next day so I came back two more days in a row but they still didn't have any.
I love DD coffee and their selective donuts. This a closest spot to my office so it's very conivent and they are open early morning just like any other coffee shop.
I would say that some times you do have to watch out for some of the homeless folks who are hanging outside of the shop. Mostly they are harmless but they can be verbally abusive at times which can make your great morning into not so great.
One great thing is they do have a pick up window for online orders.
