The best restaurants serving British food in Rother South East

We had been in Battle for a visit to Battle Castle and on the way home we popped by Camber Sands as the sun was shining, at this point we were really hungry so went to the Marina Cafe, we got Cheesy Chips for £5.45, Hot Dog and Chips for £11, Cheeseburger and Chips for £11 and Chicken Burger and Chips £10.50, 3 Cokes and an Oasis taking the total to £46.50. Our food was brought out, the cheesy Chips had a sprinkle of cheese, the burger was a cheap frozen burger with the tiniest cheese slice on it that it was barely there, my daughter said the chicken burger was dry and chewy and the chips were tasteless and cheap, so disappointed to be honest, felt completely ripped off, my partner went and asked for onions on his hot dog and they said they don't really do onions anymore as no one really wants them! And when I asked for some mayonnaise, was told there was two on the tray! Two poxy mayonnaise sachets, honestly be warned not only was tje food way overpriced but it was tasteless cheap food, we also heard other customers complaining about the food they had what they had been charged, I don't mind paying out money to eat out and get nice food, this food was like cheap basics you would buy in the supermarket, being charged at high prices
