My first time to eat Cello's doughnuts --- the outlet was zero ambience. The waitress wasn't enthusiastic even if I was engaging her to talk, since I was so excited to try a piece of their creation.
The kitchen at the waitress's back was exposed. I could see small bowls of icing seated next to one another --- it didn't look hygienic.
Glum, that's the word. No mood, no sugary spirits... The donuts were good, they were soft, comfy and sweet --- tasted like Go Nuts Doughnuts (the best donuts in the country, I think).
