I frequent the Pappadeaux in Denver which has been consistently excellent over the past 10 years.
The Pappadeaux here in Phoenix, while "never" up to the standards of the Devnver franchise, was always worth the trip. Not so on my past 2 visits, while the ambience is still up to standard, the food quality, service, and bar energy has dropped off a cliff.
The place was still packed with customers, I guess there's no accounting for taste.
I can't see myself going back.
