I'm sorry to sound so harsh, but this fourth season of "Wakako Zake" was imvho even weaker than the third one.
Except for the occasional episode featuring interesting dishes (like for example the Chawanmushi, the Maguro and the Chūka ones), most of the rest is filled with bland and/or unappealing dishes (to name but two: corndogs and a "pizza" with fries and mayonnaise....URGH! >___<). I think there's a (not so) fine line between being a gourmet (i.e., someone who appreciates good food) and being a glutton (someone who wolfs down whatever comes their way, 'cause everything is good for them). Unfortunately, seeing (the anyway totally adorable!) Takeda Rina having culinary orgasms for stuff like the sliced-tomato-with-some-oil-on-top (hardly something you'd need a professional cook for, let's face it!!! >__<) or the plain baked garlic....well, it gave me the strong impression that Wakako-san has turned into a desperate glutton, and that's sad...if they keep going down that path, I can imagine a future episode of a future season titled "Bread Crusts And A Glass Of Water"...which from a philosophical point of view could still make sense, okay....but much less so considering that we're talking of a food drama, right? ^_^;;;
