This extremely popular restaurant, open only from Monday to Thursday, requires taking a day off work to visit. I tried the limited Beef Korma Curry, and one bite delivered a shocking level of spiciness. It felt like I was eating pure spices! The heat and flavor were on par with the level 10 cold miso ramen from Mongolian Tanmen Nakamoto, which is the spiciest option. It was quite a challenge to finish it.All the other customers seemed to be regulars, casually enjoying this dish. Although I ordered level 4 spice, levels 5 and 6 sell out quickly. In a world where many curry restaurants cater to a milder palate, I’ve never heard of a place that serves such boldly spicy curry and is still popular.It didn’t seem like a gathering of spice enthusiasts. As many Tabelog users have commented, the owner, with their flashy appearance and excellent customer service, attracts a diverse crowd, regardless of gender, who seem unfazed by the heat.
