Do they have much of a selection of miniature liquor bottles, i.e., the kind that are 4 to 5 inches tall? Also, are all of the Gomer's locations about the same size as each other, or is there one that is the "main" store?

Really?

I did see some

There is also one in Lee's Summit. It seems a little bigger.

99th is the main store, the original. They have a decent selection of mini bottles, a good selection of medium and 750ml sizes of cheaper alcohol as well. The 99th one is about the smallest, Ks location is big, not sure if it still exists, nor am I sure if the 39th location still exists, if it does, it's about the same size as the 99th location.
