01 / ABOUT THE PLACE

About this place

For a satisfying fish lunch, start by choosing between grilled fish and sashimi. Koshian’s lunch menu includes grilled fatty mackerel, grilled silver salmon and horse mackerel fry set meals, as well as set meals with black tuna sashimi and sea bream. There are fried dishes and pork cutlets, too. One diner who ordered the horse mackerel fry set meal noted that it came with two large pieces, with a hint of salt bringing out the fish’s flavour. Another visitor added horse mackerel fry to a sea bream sashimi set meal, and enjoyed the fluffy fried fish alongside thick-cut, generously sized sea bream. Adding a side dish to a fish set meal is one way to enjoy both sashimi and something fried.

For grilled fish, the grilled fatty mackerel set meal is worth considering. One lunchtime visitor said the mackerel was large and thick, with a satisfying richness and plenty to eat. Someone who chose the grilled sablefish set meal also felt the generous, tender portion offered good value, and the range of fish makes it easy to vary your choice. If sashimi is the main draw, options include set meals with black tuna or sea bream, as well as a seafood bowl and sashimi set meal. One visitor wrote that they ordered the sashimi set meal with an extra-large serving of rice and braised pork, and enjoyed a varied selection of sashimi, including tuna, bonito, yellowtail, cured mackerel, octopus and squid. The pork, they noted, had a meaty texture rather than being especially soft and melting. It is a useful option to bear in mind when you want a substantial meal alongside the sashimi.

Along with set meals at lunchtime, Koshian serves small plates and sake in the evening as an izakaya. Hōōbiden Junmai Ginjo is described as balancing muscat-like aromas and sweetness with a clean finish, while Kirinzan Extra Dry is an option for those after a crisp, dry sake. It suits diners looking for a drink to pair with sashimi or grilled dishes. Weekday lunch is served from 11 to 13:30. Visitors have reported busy lunch periods, and some found that the sashimi and seafood bowl had sold out. If you have a particular dish in mind, consider arriving earlier.
