shocking pricing

My Sister in-law and I went to John Dorys at Wilsons Wharf for lunch on Sunday the 26.05.2024. My Sister in-law said she wanted the veggie platter even though this is not on the menu she has had it at Pavilion and other John Dory restaurants before. It came and she noted it did not even have what the other platters usually came with but we didn't say anything. When the bill came we nearly died. R190 for a veggie platter which she usually paid R110 for at the other John Dorys ! How can a veggie platter be R190 at one John Dorys and R110 at another and it didn't even have what the other platters had ?
