We went on Boxing Day, they were busy and the owner seemed stressed out and was a bit rude. When the bill came, he had added the tip automatically because he said we had a large group, we had 6 people in our group. However he added the tip again when I paid with my credit card. I was with family so wasn't paying attention but noticed once I got home that he charged me the tip twice. So make sure you check your bill before paying.
