The left has fire-fly squid, and the fried food is also a symbolic for Spring.... Taranome's Tempura. This is known for Spring delicacy.... bit bitter.... this food is certainly for adults.
I have heard before that these bit bitter Spring food has something which detoxes bad stuff from your body which was accumulated during Winter and refresh the body system preparing for new season. The top is cooked pork with beans.
The flavor is miso ? The right is buckwheat seeds & wasabi's stem. Yes, it is bit spicy. Bit sweet with miso or soy sauce taste.
