extraordinary authentic udon! located on kuhio avenue, you will have to park in one of the less busy streets or walk to this location. unless you go in the morning, lunch, dinner and late times always has a huge line, so assume to wait for a very long time.
however, with that said, it is definitely worth it. the reason why it takes so long is that they handmade and prepare the udon noodles, giving it the best texture and absorbency of whateverbrothit is place in. in assembly-line fashion, you let the first chef know what kind of udon you'd like to order; they have a variety of hot and cold udons, with different broths and flavors. then after you let them know which one you want and the size of the bowl, they hand the freshly made udon bowl to you and proceed down the line, where you have an array of toppings and side orders to choose from; each topping and side order (e.g. rice balls, musubi) incurs a cost, so be mindful of that.
my husband and i went to marukame twice! we ordered the curry udon, ontama udon (the one with the egg), and the niku udon. my husband's favorite was the curry udon with its decadent and thick seasonings and japanese curry flavors, while my favorite was the ontama udon - i'm an egg lover and the way they cook/poach these eggs was to die for, it was so good, and paired well with their tasty broth. the niku udon was infused with lots of beef flavor notes, and the beef that accompanies it was very tasty indeed - it was definitely close to our favorites, we just happened to like the others more due to our personal preferences. as for the toppings, i believe that any of the toppings would seriously fit and pair well with any of the soups. all the toppings we had were fried with tempura batter: the squid, fishcake, soft-boiled egg, croquette, shrimp, fried chicken, sweet potato, and mushroom. we also purchased their tuna mayo rice ball, salmon rice ball, and the musubi. all the toppings were great (just choose on your preference), and the tuna mayo rice ball was definitely excellent! we've had better musubi elsewhere, but the udon and its toppings definitely outshines here!
and what's even better was that everything came to a very affordable price - for our first visit (when we nearly bought all the toppings and side orders listed above and 2 udons), it only came out to $19.50 (with tax included) - and we had to take some leftovers home! we were gratifyingly full and our wallet did not break, compared to many other restaurants in the area.
so my recommendation is this: whether you are a local, tourist, in waikiki, or just visiting the island for one day, stop by here! the udon brings me back to my japanese days in its authenticity, atmosphere, and taste. marukame will surely not disappoint and you'll be glad you went!
