About
Isai Ramen Bistro operates in a residential corner of Praha 6 that most tourists never reach — which is exactly why Prague's Japanese expat community has made it their own. A January 2025 Reddit r/Prague thread summarised the consensus: 'Isai is the closest thing to a hearty Japanese ramen — it's run by a Japanese owner, no frills.' Multiple commenters confirmed that half the staff are Japanese and that the restaurant is regularly full of Japanese nationals. Chef Yoshi trained at Ippudo, the globally respected Japanese ramen chain, and brought that discipline to Prague's ramen scene in 2019. The menu centres on tonkotsu, shio and miso ramen, all made to exacting standards, alongside gyoza and Japanese street food. It is a no-frills, high-conviction operation — the kind of place that earns loyalty rather than chasing it.
