If you're curious about the unique term "Mentaiyaki," it refers to dishes flavored with mentaiko (spicy cod roe) that’s baked or grilled, giving a rich, creamy, and savory flair to traditional Japanese fare. Kei Kaisendon’s take on this combines fresh seafood with smoky grilled unagi, creating a sensory feast you won’t forget. Many reviewers praise Kei Kaisendon not only for their delicious Mentaiyaki Kaisen Unagi Don and Udon sets but also for their value—huge portions that feel like two meals in one, making it perfect for sharing or a hearty solo feast. The sides are worth mentioning as well; their yakitori is tender and well-seasoned, while the gyoza boasts a crispy exterior with juicy fillings. The mentaiyaki inari offers a unique sweet-and-savory bite that complements the main dishes perfectly. Located conveniently at 3 Temasek Boulevard, #02-372 in Suntec City, it’s quickly becoming a favorite spot for Japanese food lovers hunting for authentic, flavorful donburi bowls. Whether you're new to Mentai dishes or a seasoned Kei Maki lover, this place offers a hearty dive into rich umami flavors paired with fresh seafood goodness. I highly recommend stopping by early to avoid the crowd and savor every bit of this underrated gem.
