Unsatisfactory Meal

I visited John Dory's Gateway twice and was disappointed with the size and look of the prawns. They look so small and some prawns only had meat on one half. The prawns looked dirty and some were not deveined. I visited the John Dory's Cornubia mall a quite a few occasions and the prawns served were totally different. It was an enjoyable meal and well worth the money spent. I don't understand how this is possible and would not visit the Gateway store in the future. I feel this should be reviewed by the Management of the store as I'm sure I'm not the only one that feels this way.
