Flùr - the evolution of the slice from Naples to New York to Edinburgh

A look at how Scotland’s slice scene is evolving — from street‑food roots to Flùr’s modern take inside Bonnie & Wild.

Street food remains one of the fastest‑growing forces in casual dining, driven by demand for affordable, high‑quality dishes that fit modern, on‑the‑move lifestyles. Food you can grab between the jigsaw pieces of daily life — whether that’s a streetside bao bun or a fold‑and‑go slice of Margherita.

Pizza is a major player in this space. The global street‑pizza market is now estimated at $150–280 billion, with steady growth predicted. Affordability is central to its success: slice shops typically sell for £3.50–£4.50, a sweet spot for both cost‑of‑living‑squeezed diners and margin‑minded operators.

Across Scotland, more businesses are embracing the 18‑inch, sold‑by‑the‑slice format, creating a growing ecosystem of slice spots from Civerinos Slice to Sears and now Flùr Slice Bar & Pasta Bar. Food halls and market spaces have accelerated the trend, offering high footfall and low‑risk environments where slices naturally thrive.

The slice itself has deep roots. According to Wikipedia, Lombardi’s (1905) is widely credited as the first licensed U.S. pizzeria, selling whole pies for five cents. Many customers couldn’t afford a full pizza, so they paid for a slice proportional to what they could spare — wrapped in paper and string.

In Scotland, pizza arrived with Italian immigrants, and in 1965 Peter Boizot founded Pizza Express, bringing an oven from Naples and introducing authentic thin‑crust pizza to London. That moment sparked everything from chains to takeaways to supermarket frozen aisles. Then came the artisan new wave — and, the latest iteration, slice shops, with their focus on fermented dough and premium ingredient toppings.

Flùr brings together founder Ivan Stein’s (The Gannet) vision and Anthony Falco’s global pizza expertise. Falco has helped shape Flùr’s long‑fermented, Scottish‑milled dough and New York–style approach. The result is a slice offering that blends international technique with local ingredients, delivered in a fast‑casual format inside Bonnie & Wild.

I visited with my Italian friend Eleonora, and we ordered four slices from the minimal menu (good for reducing food waste). We praised the signature crispiness and enjoyed the buzzy vibe and friendly pizzaioli. The tomato sugo leaned a little acidic for us. I loved the Nduja and Honey with its nuggets of fiery sausage, sweetness and smoke. We also tried the Pasta Arrabbiata — the pasta was slightly overcooked, but the sauce was simple, gently fiery, and excellent with a “tennis ball” of oozy burrata on the side. the carbonara also needs checking in out in the future.

Bonnie & Wild has its own charm whatever the weather, and Flùr is a strong addition to the line-up. With pasta around £12, burrata at just £6 (when we visited) and slices topping out at £4.50, you can pop in for something tasty and filling without breaking the bank. 

From the slice’s humble origins to modern life “Tutto cambia perché nulla cambi.”
