Kelly's Country Store
We would visit Santa there and usually buy a couple of ornaments and some candy. We almost always got sponge candy or orange chocolate (both pretty much unique to Buffalo, something I had never before realized til I moved to Maryland and couldn't get any) and one year, I picked out little paper Victorian-style angels for my ornament. I still have a few, but they are in storage stateside.
They had a great holiday display, it took up the better part of the back of the store. It was great! At least, it was when I was a kid. Revisiting it as an adult, it was okay, but looking a little frayed around the edges. That holds true for all things you visited when you were a kid--the Country Store, the local amusement park, Casa Bonita (Chris). Still, it's all good.
They had the best candy, though and the clerks would always give you a free sample.
