This was a beautifully written story. I particularly liked the worldbuilding with the bartender who can create drinks that dredge up memories; it's a great expanded fantastical take on something that people try to do at bars with alcohol (i.e., get lost in their thoughts/memories) in the real world. The story was well-paced and moved along briskly despite covering a fair amount of information, and the amount of detail description in the prose was just enough to create a vibrant picture for the reader without slowing down the pace of the read.

I found the lack of proper punctuation around the dialogue a bit hard to follow along with in certain places. It seems that it was a stylistic choice for this piece (it's too consistent to be typos/technical errors) and while breaking the rules can sometimes be effective or even accentuate the piece, in this case I thikn it was a detriment because there were several passages where I had to go back and re-read them, not realizing they were someone's dialogue. Adding in the correct punctuation would help the flow of the read even more, I think.

I was also hoping for a bit more exploration from the narrator. The world you've created with the alcoholic alchemy is so creative and interesting, and yet the srtory only really delves into one memory and has the narrator contemplate a second. I would have loved to have seen this story explore that dynamic in more depth; maybe he does try a memory drink he doesn't like and returns it, or wants another of the same, etc. As it exists right now, the narrator is in a bit of a contradiction where he seems eager to sample different drinks, but then only really focuses on the one. I think having the character go more intentionally toward one side or the other would round out the story a bit more.

Although there were a few areas for improvement (suggested above), I thought this was an excellent piece that was well written, well considered, and leaves the reader with a feeling of nostalgia and even a bit of wistfulness. That's not easy to do with a piece this short, but you sure managed to make it look easy. Nice job!
