Japanese curry is quite a popular dish. One derivative of it, soup curry, contains more broth and is more “watery.” In many restaurants, it is their primary dish. When first ordering, you have to decide which type of soup base you want. Many places only have 1 choice while others may have either the traditional curry soup base or a tomato base. Next, you can decide what type of “meat” you want, i.e. chicken, pork, or seafood; vegetarian is an option. Then, you can pick how spicy you want it with options ranging from not spicy to eye-watering. As for rice, you can (sometimes) choose between white or brown rice, and you can choose the size of the rice.
I have also recently discovered the goodness of lassi (don’t know how I didn’t know of it beforehand). It is such a great way to temper the spiciness of the curry as I sometimes overestimate my spiciness-threshold.
