This cafe was recommended to us. We all had cooked breakfasts before travelling back home from a short break in Cardiff. Lovely people, delicious food, free parking and very clean. Highly recommend View all feedback.

Elderly women at the counter doesn't listen! I stated my order twice, she still got it wrong then had attitude when I sent food back, made out it was my fault, poor service, poor food, waste of money.. never again. View all feedback.

A proper cafe that doesn't try to be pretentious. The food is really tasty and the prices are very reasonable. I had the large breakfast and it's really was large. Coffee nice and hot and the service was quick. If you want simple food, done really well and at a great price, you won't get better than this cafe. I can't recommend it enough. Price per person: £1–10 Food: 4 Service: 5 Atmosphere: 4 Vegetarian offerings: Vegetarian menu or section

Typical greasy spoon cafe. Price was OK, but the quality wasn 't great. The woman taking orders at the counter should try learning some basic hospitality skills, like how important it is to greet customers and say 'thank you ', instead of just grunting at them like they 've disturbed her. Price per person: £10–20 Food: 1 Service: 1 Atmosphere: 2

I ordered a baguette, but it was microwaved and ended up being soft and soggy. However, the other meals being served at the restaurant looked delicious.
