This would make it only the 3rd Japanese restaurant chain in about 40 years that I know of to come to Colorado
The others were Yoshinoya (Beef Bowl) back in 1975, Gyu-kaku in 2019 (Also near Union Station), and now Jinya Ramen Bar a Japanese/Japanese-American chain.

If you want to learn more about Japanese ramen chains, check out my blog post “These Are All the Major Japanese Ramen Chains in Los Angeles That Are Responsible for Ramen’s Popularity in the U.S.“
If you’re excited to finally have a Japanese ramen chain in Colorado, be sure to follow Oishii-Desu for the latest news/review (this is the review of my first/second visit to Jinya).
