Both revolve around a main character or location and then tell the story of the person through various short stories. If you liked the style of storytelling with Namiki, you'd definitely like Bartender as well.
Both Shinya Shokudou and Bartender have main characters who embrace both its characters, and the reader in a very warm, and almost family-like way. In each of these great manga, you really feel the soul of each person who walks through the doors of the shop in each respective manga, and from both these manga, you learn about life and all of its shortcomings, and how to sail past them. I sincerly recommend Bartender, if you liked Shinya Shokudou.
Both stories about about talented and mysterious people(who are masters in their own worlds," Mushi Master" in Mushishi "Glass of the Gods in Bartender") who throughout the story help solve all sorts of people's problems(Mushi in Mushishi, Cocktails in Bartender)
