Ordered the Hitsumabushi 'set' ($29.50) at Man Man Unagi restaurant. There's 3 different ways to consume the Hitsumabushi. Feel free to ask the friendly staff there :)

Super delish unagi eel with slight burnt flavour from the grilling 🖒

Man Man is probably my fav out of the 3 unagi specialty restaurants in Singapore.
Do head down early (we went down to queue at around 530pm to get in at 6pm when they open) otherwise you might have to wait 1.5h in line (this happened to me when i visited them at 630pm once)
