Story
Well, there isn't really a story. Each episode stands on its own. Sometimes previous characters become storytellers, but you can watch them in any order (except for the last one). So don't expect some special development.
Each story of its own has its uniqueness. It combines elements of life with alcohol. You can believe it's really idiotic at the end of the day, but they made it beautifully in the anime.
Art
Ummm... Nothing special for both sides.
Sound
Some soundtracks were nice, I guess... I didn't like the opening.
Characters
Each character has his\her own special characteristic, past and status, as well as their special problem, needs to be solved.
The character you see most is... you guessed it right, the bartender, Ryuu. In a way, he's like a magician. He has a solution for everything, he can guess everything. But we also get the idea that it wasn't always this way. He reads people so easily it's scary, but it has some beauty in it. Who never wished he could just tell things about people by looking at them?
Enjoyment
Well, as you might remember, in the end, it's an anime that has close to zero relations between episodes, so it's pretty soothing. You don't need to rush anywhere, you're never about "What's going to be in the next episode, I really wanna know!", which makes it pretty relaxing. It doesn't fill you with strong emotions like many media try to, but it does inflect you with emotions, but the nice side of them.
Despite having nothing with alcohol in real life, it was nice to hear the story of many different kinds. Not something I'll remember, but hey, it's interesting for that moment.
And... a surprise at the end of each episode.
