New Construction. I have an open kitchen with a pass through bar top. 1/2 of the bar top faces the dining room. 1/2 faces the living room. All outlets in the kitchen are GFCI protected including the outlet on the wall (pony wall) that faces the dining room. The other outlet on the same(pony wall) is NOT GFCI protected. When I questioned the electrician (licenced) about this, he said that the (pony) wall that faces the living room is not considered a pass through to the kitchen. I say that this (pony) wall is a pass through to the kitchen and it needs to be GFCI protected. What is the skinny on this??

The elctrician is correct. The GFCI is supposed to protect you when you are in the kitchen where you can touch water pipes/fixture and faucets while touching an outlet.

Actually neither or your electrician are correct.
ONLY receptacles serving counter spaces require GFI protection. You can do anything you want above and beyond that.
