I dont hate it, but the manga has problems. The healthy food stuff is interesting, but the isekai part of it is rather underdeveloped and lazy.
Its weird to go to another world, but still refer to all the ingredients with their earth names. I get that its a port city they are in, so they probably get access to all sorts of foreign items. But chinese onions? really? couldnt have come up with a different name for the isekai veriant at least??
Also that dragon god mascot looks like it was copied straight from grandblue, and sometimes doesnt even show up like it was forgotten about.
Basically if you love food manga you might get something out of this manga, but if you came for the isekai you will likely be very disappointed.
