I've been to Nan and Byron's several times and give them a solid 4 stars. Lunch is great - the meatloaf, tacos, French dip are all stellar. Their restaurant week menu was lovely. Brunch is a standard Charlotte brunch buffet, nothing too amazing there. But if you're looking for quality, no frills brunch convenient to the South End area - Nan and Byrons is worth a stop. As far as service goes: when they're good... they're GREAT, but it's been hit or miss in my experience.
