Aisle A

Oddly, before the main aisle numbers start, there's "Aisle A"... which is actually two aisles, with a strangely narrow coffin case in the middle for half of the aisle, and with their own unique decor (aisle markers, category markers, and a couple interesting curved projecting things sticking out of the shelving to one side). Since this area is under the low ceiling, I suspect it would have been part of QFC's produce department, with the aisles starting where the higher ceiling starts; most likely, H Mart decided to add these couple aisles later and didn't want to adjust any of the other decor to match. (Though they could have at least signed them as A and B, so there wasn't just one random lettered aisle that's actually two aisles...)
