Lock No. 4 is an Ohio-based coffee shop with specialty drinks and snacks. They recently opened a Vienna location, complete with drive-thru.



I ordered a frozen hot chocolate because when I had one from Tim Horton's, I was a big fan. I can't say I was as crazy about this one; I don't think it was blended as finely as it should have been, and it needed more flavor to combat the ice watering it down.



The featured donut was OK. A donut has to be pretty special for me to get excited. This was fine - probably better paired with hot coffee.
