I often hear raves about the generous portions of fish and chips, a staple that never disappoints. Diners love the crispy battered fish, expertly cooked to meet expectations every time. The chips? Golden and fluffy, customers rave about the perfect texture.
Another highlight is the exceptional customer service. There are heartwarming stories of the owner providing complimentary meals to patrons waiting longer than expected, creating an unforgettable experience. It becomes clear that community and quality food are top priorities here, fostering a loyal customer base that keeps coming back. Lastly, the convenient delivery and takeaway options are lifesavers for busy lunches or evenings at home.
Most Disliked
Despite the overall high praise, some diners note the occasional struggle with parking, particularly during peak dinner hours. It can become quite competitive as locals seek their fish and chips fix during busy times, especially on Fridays.
Additionally, while the atmosphere is typically lively, a few visitors mention that it can feel crowded during peak hours, potentially leading to a slightly rushed dining experience. For those who prefer a more relaxed outing, arriving during less busy times, typically during lunch or early dinners, may offer a more comfortable and enjoyable experience.

I came to collect a UberEats order and had to wait a while for the order and the friendly owner gave me free fish and chips on the house for the inconvenience which truly shocked me because I been doing fast food delivery since 2019 and no restaurant has ever given me anything for free. I’m not being biased when I say this but this was the best fish and chips I ever had, it was nice and soft and cooked perfectly. I wouldn’t mind spending my hard earned money on buying food for myself or my family from this shop

So my brother is always raving about this place (as its his local) decided to give it a try and pleased to say I was not left disappointed (or hungry) i went for a regular portion of fish and chips and as you can see from the picture the fish was massive. Chips were also very nicely done. Did not find a single bone in the fish and the batter is delicious, buttery and soft but with a crunch to it. Excellent

Mario’s Fish and Chips is truly something special. As someone who works for Rick Stein – where we cook thousands of portions of fish and chips – I can honestly say Mario’s stands out in the best possible way. I usually order the British sausage and chips, something I used to be quite hesitant about. But Mario has completely changed my mind – it’s absolutely delicious, perfectly cooked, and full of flavour. He’s turned something I once avoided into my go-to order. That says a lot! You can tell there’s real care and pride in every portion, and the personal touches make all the difference. The mayo on the side? Spot on. Thank you for that, Mario! Well done, and keep up the amazing work – you’ve definitely got a loyal fan here. – Adam from Barnes

Great tasting fish and chips, the chips are fried perfectly so that they gave the perfect crunch and potatoey goodness inside. One of my favourite fish and chips shops in the area.
