I'm watching Food Wars based on a number of recommendations, and it's pretty good. It's addictive the way that anime can be.
I haven't watched a straight faced shonen / battle anime in a while, so it took me a while to really warm to it. I think that it gets a lot better after the first 4 episodes or so (basically, when he gets to the dorm and you meet the full cast). For one thing, having more characters rounds it out, but they also zeroed in, I think, on how to make the food fights work.
I had a hard time buying the first challenge (entrance exam), because there was a little too much "masaka!?!" I'm sorry, but the finest chefs in the world wouldn't be dumbfounded by aspic on rice. I think they made a couple changes after that to make it work better. They stopped focusing on surprise ingredients or techniques and focused more on the emotional experience, (e.g. "It tastes like the first day of spring") which is easier to justify. I realize that it's part of the suspension of disbelief, but it's pretty hard for me to buy the shock and awe parts.
I've also been thinking about what it is about the show that I actually enjoy, and I think a big part of it is just camaraderie-porn. Soma's surrogate family is so supportive and...generally upbeat and pleasant. It's really just kind of nice.
Honestly, they haven't quite nailed how to render the food without making it look slightly gross and plastic. They try to give it a photorealistic sheen in show cases, but it doesn't really work for me. I recall that making the food look appetizing was a huge challenge for Ratatouille (which they only kind of solved), and it's clearly still a problem. Although not really a problem, because again, focusing on the fictional experience of eating it rather than trying to sell it just through the visuals works better anyways.
