Came here for lunch on a Wednesday and was seated by the window for a table of one immediately. Although there were other customers in the restaurant, the service was always quick and the food was hot.
The restaurant itself isn't large and could fit approximately 30 people in total. I ordered their lunch special, which is available from 12-3 for $13.99. You get a set Hakata Tonkatsu ramen (topped with green onion, black mushrooms, two pieces of char siu, and bean sprouts) and a choice between either Fried Chicken with rice or more Char Siu with rice.
I ordered the fried chicken with rice and in about 5 minutes, my rice had come! It was a small portion with 3 pieces of chicken topped with Japanese mayonnaise, green onions, and chilli flakes. The rice was lightly soaked in sweet soy sauce. It was quite pleasant and THE highlight of my meal! The Hakata Tonkatsu on the other hand, was not as great. The noodles were too tough and took a while to take in the heat from the broth. The broth was nothing spectacular and was very meh. I would've personally liked different toppings with my ramen (like corn for a hint of sweetness). The two pieces of meat were also quite standard.
I think I would have to come back only to order the rice... which was BOMB!!
