Wakako-Zake is a food manga by Chie Shinkyu. There's not much plot or characterization, but that's made up for by a lot of eating and drinking. It's a much simpler concept than Oishinbo. Nobody's lecturing or crusading for industrial standards here, just Wakako thinking about what she likes about the meal and then letting out a long breath of satisfaction. The manga has been made into an anime and, as you can see, a live drama. Read a review.
