DNG is very comfortable and, excluding Fridays and Saturdays, it's always easy to get a table. The club sandwich is tall and tasty and the seasoned fries are awesome. Service is a little slow at times but always friendly.
Sunday brunch draws a huge church crowd, so yes, it's packed. But as of March, I noticed they now serve brunch 7 days a week. The omelets are great. Bacon can be a little undercooked. (Which seems to be a North Carolina thing because I can't get truly crispy bacon anywhere except at diners.) And their grits look like cheese grits but they aren't, and they're still really good.
