Had groupon voucher which iv had many times befor and told lots of people how wonderful wynard hall is.. It was always very good food and very good service .. Today for some reason i was there with 7 friends and it was very disappointing food and service was terrible dont know how this has gone down in such short time . Im very upset as i took friends for birthday treat, Somthing needs to be done as people will stop going.. Thy said we stopping doing dinner vouchers but why give us poor food and service
