I visit a Donut Delight for coffee and Breakfast 4-5 times a week.
The Elm Street (stamford) Donut Delight has always done a great job as far as service and product delivery are concerned but they are always so busy especially the drive thru.
I had a few poor experiences here on West Ave but they have been consistently GOOD for about a month now. My coffee is perfect the food is prepared correctly and I am not delayed any at the window. They may have just grown used to me/my order and know to put the proper things in my bag so I can just grab & go. In any case.
The service has significantly improved.
