Yoidore Koi o Sezu
Unemployed and unable to find a job, Misumi drowns his feelings in sake and a one-night-stand with a handsome stranger he knows he'll never see again--only to encounter him at a soba restaurant a few weeks later. Sei gives Misumi a job as sake master in his restaurant and allows him to live above the restaurant with him. Their physical relationship resumes but Misumi, who has been burned by straight men before, is reluctant to grow closer to him and pushes down his feelings until someone from his past surfaces. A+ for slow build, good pacing, FABULOUS work details. Sometimes you know an author has no real idea of the industry where a character works, but that is not the case here. I don't know anything about sake but appreciated the little bits of information in this manga. This is definitely a story I will re-read! My only complaint is I would've loved a bit more of them together in the final chapter. ETA: There was a short 12th chapter added later, where they get to be a bit lovey and intimate!
Boku no Kawaii Yopparai
Good premise: quiet coworker in love with new/handsome/polite coworker and drunkely confesses after the welcome party. Unfortunately, we saw very little of the emotional build, so the intimate moments held no weight. There was a bit of build on Chii's part in a later chapter, when we got his point of view, but I wish the story had been told a little differently so I could've watched them fall in love. Pretty art, though!

Chara Cafe Relish Ni Oide
With his older brother's restaurant in peril because of few customers, a student uses his nights to sew costumes for a bunch of hosts who have agreed to work as cosplay waiters without pay in exchange for room and board. One of the hosts hits on the student and they have a lukewarm relationship. I agree with the other commenters: I would've rather read about the older brother and the other host.

Umi To Futari No Enbun Noudo
College student Ryuuta returns to a restaurant summer job with the intent of finally saying goodbye to Nao, the owner he's loved one-sidedly for years. But he finds Nao newly single and heartbroken, having been suddenly left by Hana, his long-time girlfriend. Seeing his chance, Ryuuta confesses to him, but Nao isn't ready for a relationship and is stunned that someone he considers a brother is in love with him. They take things in stride, giving Nao time to heal and grow closer to Ryuuta, which he does in a gradual and believable way. The feelings for his ex linger, as feelings do, but this is mature and satisfying.
