Sick guests after eating at flames restaurant

Last night i went to the flames restaurant for a friends birthday dinner (08/03). When we got there we were served with drinks and starters and placed our orders for main meals. We waited over an hour for our food to be served and noticed our table was being neglected and was told that our food would be late over and above the hour we already waited. When the food arrived it arrived cold and one meal was rushed and cooked which looked very watery so we sent our meals back to the kitchen, having to wait longer. We then realised another table was waiting for 2 hours for their meal and was told certain items on the menu was out of stock. One of the meals ordered had actually made a friend throw up and he was not able to eat his meal and was off sick from work the next day. After chatting to the other table it was noted that 3 of the chefs resigned 4 days ago, which really was unacceptable for a fine dining restaurant to not have chef's available and then to serve food which actually made their customers sick, although some of the meals were taken off the bill, a persons health and safety should be a restaurants main priority and if they were not able to handle capacity then guests should have been informed upfront. This was the most disappointing experience i have ever had at a fine dining restaurant and no guests should be eating there if they become sick and dont have appropriate chefs cooking the meals.
