The American woman, Karissa, tried British fast food and shared her thoughts on Instagram. She is from the US, where fast food is very popular.

Karissa first tried Pepe's Piri Piri, which people said was the best fast food chain in the UK. She had chilli-loaded fries and extra hot chicken and rice.

Karissa said the chicken was delicious and spicy. She gave it a score of eight out of ten. The chicken was tender and the garlic sauce was creamy.

Karissa was not sure about the fries at first, but she liked them. She gave the fries a score of seven out of ten. She wished there was more cheese on the fries.

Next, Karissa had a quesadilla, which was filled with moist chicken. She said it was very good and gave it a score of nine out of ten.

Karissa then went to a chippy, a British fish and chip shop. She did not have fish, but instead had a battered pizza.

The battered pizza was not what Karissa expected. It was more like a bread crust than a crunchy one. She gave it a score of six out of ten.

Karissa was surprised that she could buy a battered Mars bar at the chippy. She liked the soft center, but it was not crispy on the outside.

Karissa said the battered Mars bar was warm and sweet, but it needed a sauce. She gave it a score of six out of ten.

At the chippy, Karissa also had chips and curry sauce. She was expecting a traditional curry flavor, but it was not what she got.

The curry sauce was tangy and vinegary, not what Karissa expected. She gave it a score of four out of ten and said the chips were better without it.

One person commented on Karissa's post and said she should try Pepe's when she is drunk for the full experience.

Another person said that the only good thing Karissa had was the quesadilla.

A third person did not like the idea of deep-fried pizza and said it was not a typical English takeaway food.

A fourth person said that the chip shop Karissa went to did not seem very good and that she should try a different one with better curry sauce.
