Poor quality Restaurant and Food

The T-bone that was served was poor Quality meat and untasteful. My wife was sick and still is after the seafood pasta meal she ate - we had to get medicine after our visit at a Restaurant, how is this acceptable for management and the owner? The waiter and a manager was made aware of this but nothing was done - how does this Restaurant protect the customer from this? Consumer Protection??? Please call me on 084 207 9522 to arrange a full refund, otherwise I will have to discuss this with the NCC
