5 /5 Thomas Moore: Wow! My friends and I ordered the fish and chips and we were amazed at the portions. It was a little on the steep side at 17 pounds for a small portion and 18 for a large portion, but it was worth the price. A small portion here was still twice the size of a standard fish and chips in the US. It kept me full until lunch the next day! I was skeptical when a British friend of ours told us to try the mushy peas, but they were actually quite excellent. The fries were okay, but there are tons of dipping sauces to choose from. I also tried fish and chips at The Castle Pub, and while those were good, Posh Fish is better.
