The Mermaid Cafe (マーメイドカフェ, Māmeido Kafe?) is a restaurant in Coral Hill on Fishman Island. It is owned by Madame Shirley. Keimi and several other mermaids work here.[1] The cafe's employees all live in the same dormitory in Mermaid Cove. It first appeared in Chapter 610.

The cafe's menu includes: cake, sea fruits, wakame seaweed brulee, mozuku seaweed tarts, konbu kelp souffle, shellfish meat, scallop sandwiches, and shijimi clam pizza.[2]

The cafe is apparently very popular, as one of Gyro's crew member's dream was to visit it, and was incredibly disappointed to be deprived of it, despite the danger they were in.
