I noticed recently that Daynight Donuts has some new "painted-on-the-window" type signage up at the triangle intersection where Commercial and Liberty Streets come together. This is on the north end of downtown as you are headed to or from the Salem Parkway, just north of O'Brien Auto. I hear they are opening a second location. There is going to be some remodeling on the block which will add a bit more parking as well.
Also, a bit of a mystery was solved for me when I Googled "Daylight Donuts" instead of "Daynight Donuts" accidentally (I know! How could I make this mistake?!?). Apparently, Daylight Donuts is another small chain of donut franchises started in Tulsa, OK. They currently have about 1000 franchises. I bet when Daynight first changed their name to Daylight (this being after they changed from Dunkin Donuts. Follow that?) they found out that the name was already taken by this other franchise.
So, tada! We now have Daynight Donuts. With a second location coming soon!
