Next time you are looking for a culinary experience in Tokyo, I suggest this one. This restaurant in Asakusa is specialized in Dojo, a cute little fish that lives in ponds and rivers of Japan.
River fish have a reputation of tasting more muddy than their saltwater counterpart (like those used in sushi), but with proper cooking can be delicious as well. I’ve heard those little dojo loaches are cooked in sake and become quite drunk before leaving this world, that might just be as well the reason they taste so good!
Plenty of locals from grandpa’s to families eat there: I think you should go as well!
