I've two favourite otah stall in Singapore, and this is one of it.

The mackerel used is fresh and you could taste its delicate sweetness, because the spice used isn't overly spice though fragrant. Although the fish paste and spice used is the same, the $0.60 version is more smoky while the $1.20 version is more moist. The difference is due to the use of different types of leafs used while grilling the otah.

Those who wants their otah to be more spicy may instead visit Tan Beng. Both serves great otah for different reasons!
