Fat Hippo Cardiff is a burger restaurant on Church Street in the city centre. The ground floor venue includes a heated outside seating area and welcomes bookings as well as walk ins. Its deliberately informal style suits quick lunches, family meals and lively group visits.
Signature beef burgers use double patties as standard, while brined buttermilk chicken brings a crisp alternative. Rich sauces, cheese, pickles and playful toppings create the bold combinations associated with the brand. Dirty fries and other loaded sides turn the meal into the generous, hands on experience Fat Hippo describes as the good kind of gluttony.
Vegan burgers, vegetarian choices and a menu based on non gluten containing ingredients broaden the selection. A children’s menu serves younger diners, and all facilities at the Cardiff restaurant are on one accessible level. Allergies should still be discussed with the team because peanuts and other allergens are present on site.
Shakes, soft drinks, beer and cocktails match the richness of the food, with desserts available for diners who want a longer meal. Collection and delivery provide alternatives to the dining room. Fat Hippo Cardiff takes a focused burger format and gives it range through beef, chicken, plant based choices and a substantial list of sides.
