Pizza made at a Castlemilk business park is unlike any I've had before

If you're an avid social media user (or up to date with Ron Mackenna's latest reviews) you might have already guessed that this evening I'm on my way to Sub Rosa in Castlemilk.

Or at least I hope I am, anyway.

The latest venture from the talented team behind Canotto, this place has become something of a viral sensation thanks to the novelty factor of its business park setting and a menu that would surely entice diners even if it did belong to a more traditional restaurant space.

Sampling the rounded Rosa and Bianca creations from Sub Rosa last month, our food critic described the food as 'not exactly normal' and then 'real revelation'.

High praise indeed, but there was noticeably one speciality item missing from the review due to its continuing sell-out success. 

It's the all-important, Detroit-style pizzas that bring us to this funny little unit warmed by the orange glow of electric heaters tonight.

Crossing our fingers in the hopes that the last of these precious deep-dish pizzas has not already been snatched up, we take our seats right by the pass, where one of only three staff members is in a jovial mood, looking very much at ease in this peculiar kitchen setup.

We're in luck, and shortly after picking two cans of soft drinks from a tall fridge over in the corner, our order is relayed to the chef.

That will be the Rosa option with Fior Di Latte, tomato, aged parmesan, 24-month aged parmesan, unfiltered extra virgin olive oil, Calabrian oregano and the extra additions of serrano ham and Guindilla chillies, please.

Likely due to the electric ovens used here, it will be a while before our food arrives, but that's no matter. Despite knowing what we were in for with the aesthetic of it all thanks to some Instagram snooping, there's still plenty of fun factor.

Why are there Lego figures and constructions dotted about as decor? I've no idea. I guess the team must be Oasis fans thanks to the large poster hanging from the white brick wall to the left, but given a lack of a cohesive theme, there's no way to be sure.

I'd love to pick the brains of the folks who decided this was the perfect spot for their new venture, but that will have to wait for another time because, for now, our pizza is here.

And what a beauty it is. So much so that the two other couples who have arrived in the past half hour have their eyes fixed firmly on the metal tray it's carried on until it's placed in front of us.

'We'll have the same', one pair will say shortly after when it's their turn to order.

The inescapable first impression is that there is a lot of food here. Even though suggested as a sharer, this deep dish rectangular pie cut into six chunky slices merits an ambitious appetite.

It's gorgeously crisped until a dark shade of brown around the edges thanks to the time and care taken by the pizza chef on duty and what I suspect is a liberal amount of good-quality olive oil.

Atop of a thick blanket of mozzarella that provides a hugely satisfying 'cheese pull' are baked slices of salty ham and slender Guindilla peppers that stealthily build in spice with each bite until you're left with lips that tingle.

The sauce is a winner too, with a little more character than your classic Italian sugo to hold its own against the main attraction: that pillowy base so thick that it could easily pass as a hefty hunk of focaccia. 

I'll admit that I was unsure of this monster at first, given that I'd usually favour a thin and crispy or stretchier sourdough alternative. But Sub Rosa's pies are in a different league altogether.

Yes, the traditional pizza flavours are there but a Detroit twist offers an entirely new experience.

It's big, bold and surprisingly moreish, especially those corner pieces that have been hit with extra heat so that any excess cheese has evolved into a tangy, savoury skirt frayed around the edges. Then there's a scattering of white and black sesame seeds underneath, toasted by the pan to add a depth of nuttiness.

We surprise ourselves by managing to get through two hefty square slices each before admitting defeat the final portions boxed up to be tackled the next day.

This is of course not the only place to find this sort of pizza on offer in Glasgow at the moment, with the likes of the Pizza Cult in the Barras or 313 in Merchant City also known to dabble in the Detroit style.

But paired with the eccentric concept and location unlike any other, a meal at Sub Rosa is one you won't soon forget.

Sub Rosa is located at Unit 34, Enterprise Park, 147 Drakemire Drive in Glasgow.
