International Plaza is probably better known for being an office tower with a retail podium in its first level that is filled with a myriad of F&B options to satisfy the hungry office workers of the Central Business District — with that being said, the building also does feature a fair share of dining options in the second level; these dining establishments mainly offers Japanese fare despite some of them serving up local and Korean fare as well. One of the latest additions to International Plaza would be Ichiwan Don — these folks can be found at the second level of International Plaza being located in the same area as where one would be able to find Enishi. Ichiwan Don does have a good amount of dine-in seats that features a mix of seating around the counter as well as regular dining tables and chairs. As the namesake of the establishment suggests, Ichiwan Don is an establishment that focuses much of its Donburi options — it does offer Donburi featuring raw fish as well as those that come with cooked elements; those whom prefer noodles can also find two Ramen dishes on the menu as well. Ichiwan Don also does offer some side dishes too on its menu.

The Donburis at Ichiwan Don are being sold as a set; this also means that all Donburi orders do come with a salad as a starter, a bowl of miso soup and a small platter of fruits. Ichiwan Don does not describe the elements that comes with their Donburi offerings; with that being said, it can be observed from our order of the Bara Chirashi Don that the dish does come with an assortment of diced raw fish mixed with Takuan (i.e. Japanese pickled Daikon radish), cucumber and Tamago — all of which being topped off with Tobiko (i.e. flying fish roe) and Negitoro (minced raw tuna). Everything sits above sushi rice that has been sprinkled with Furikake over the top. Digging into the bowl, the assortment of raw fish does come pretty chunky and fresh; there is a good variety of fish that gives a slight variance of textures and flavours while the inclusion of Takuan and cucumber adds an element of crunch and kept things refreshing especially with the former giving a slight tang — the Tamago being the element that provides a softer texture with a sweeter note from the use of Mirin (i.e. Japanese cooking wine) during the preparation process. The Negitoro adds a more fibrous texture to the Bara Chirashi Don — a big plus here considering how most Bara Chirashi Don from other similar establishments would likely having skipped this element, while the flying fish roe gives the entire bowl a popping sensation as one chews into them. The diced cubes of raw fish does come slightly chilled, and this goes well with the room temperature sushi rice that also helped to maintain the temperature of the raw fish — the sushi rice being pearly and sufficiently sticky with a slightly sweet note also from the addition of Mirin in the preparation process, while the Furikake gives the rice an extra umami touch.
