From your username I'm guessing it's the good old Air Atlanta 757's you'll be operating for Excel? If so, yes, the aft galley IS a nightmare!
Also on two of the aircraft (ARI and ARD I think) there are hardly any stowages in the fwd so you have to walk all the way to the rear everytime you want something from the crew cannister! Saying that I worked on 75's @ Britannia for 3 years and their's are configured for optimum crew friendliness!
Hope this helps
