Plant-based smash patties, gluten-free buns, and proper veggie burgers β not afterthoughts.
FlameBox started in 2023 as a one-pan smash-burger stall outside a pub. Two mates, one cast-iron, and the conviction that a Β£4 frozen patty was an insult to a proper burger.
Two years on, we've moved into a proper kitchen, added pizza and sides, and we still grind our own beef on Monday morning. No suppliers' frozen mix. No "heritage" gimmicks. Just food we'd queue for ourselves.
Try the OG Smash β"Honestly the best smash burger I've had in years. The OG with extra cheese and a side of buffalo fries is the move. Ready exactly when they said."
"Found this place on TikTok and ordered the Spicy 'Nduja. Bin the chain pizzas, this is the real deal. Hot, fast, fairly priced."
"Vegan options that aren't just an afterthought β the Green Goddess actually slaps. My partner (definitely not vegan) finished half of mine."
