Unacceptable Service

I went to John Dory's on the 1st Jan 2016. On arrival i was told that there would be a 20 min wait due to them being short staffed. We arrived at 13h20. At 13h35 we were seated and placed our drinks, starter and main meal orders. At 14h45 our starters arrived ONE at a time. We literally watched each other eat. At 15h30 we eventually got served our LAST starter, by this point not 1 waiter or manager had been to our table since 13h45. At this point called for a manager and was promised the service would improve. We still were not offered another drink or had our plates from starters and glasses cleared off our table. We ordered ice creams for our kids and they came to our table melted and incorrect, i have taken photos.The manager promised he would personally attend too us. 3 hours into our visit to John Dorys we had ONE drink and ONE starter served in drips and drabs. At 16h15 the manager had NOT assisted us as promised so we cancelled our main meal order and left!!! I have a 7 month old baby and by the time we had left she was screaming blue ****** as she was starving and i should have been at home to feed her! We are on holiday and it was so disapointing!!!!!
