Soma Yukihira's old man runs a small family restaurant in the less savory end of town. Aiming to one day surpass his father's culinary prowess, Soma hones his skills day in and day out until one day, out of the blue, his father decides to enroll Soma in a classy culinary school! Can Soma really cut it in a school that prides itself on a 10 percent graduation rate? And can he convince the beautiful, domineering heiress of the school that he belongs there at all?!
Fundamentally, they're completely different. Bambino focuses on Italian cuisine and delves into a restaurant's inner clockwork, from the main floor servers to the kitchen cooking while Shokugeki no Soma spreads it's wings with Japanese cooking, Italian and about a half dozen other nation cuisines.
Nevertheless, both focus on food and it does that exceptionally well. You can just see the passion pour from the page as meals and prepared foods are presented with gorgeous art and scrumptious descriptions, and some of those descriptions go on for lines, about the food and even some history about the ingredients from time to time. Pretty sure this is research done right.
These two are some real good food manga, character development and comedy occur with some real good bouts of intensity but first and foremost are the chefs and the meals they prepare with the soul within both. Doesn't get much better than these two.
