The short of it: new management and wait staff. Don't go. The staff, while nice, is green. Coffee was served cold because they didn't know how to turn on the warmer. The kitchen must also been new staff as well, and a bit inexperienced. We went for the brunch they now serve on Saturday's and got the sausage gravy over biscuits. The home fries that accompanied the plate were wildly over seasoned. I could enjoy the extra flavor, but their season was mixed heavily with salt and made them almost inedible. The biscuits didn't live up to my memory of past meals here. I have no proof of it, but I question how much was prepackaged compare to house made.
Until they get their legs underneath them, wait it out. Staff mentioned they will likely be changing the name soon. That ought to be a good indicator of the level of change PeachTree has gone through.
