On Colombo Street in Sydenham, Christchurch, The Serious Sandwich does one thing with total commitment: sandwiches. You'll find it inside The Colombo at 363 Colombo Street, and the name tells you exactly how the team feels about the format — lunch's greatest invention deserves to be taken seriously, from the first slice of bread to the last bite.
The shop was founded in 2011 on a simple philosophy: a sandwich is more than just a meal, it's an experience. More than a decade on, that idea still runs through everything here, from the way ingredients are chosen to the way each sandwich is put together with care and attention to detail. The team describes itself as serious about quality, and the menu is the proof of it.
That seriousness also means range. The menu deliberately spans both ends of the sandwich spectrum — classic favourites and innovative creations, as the team puts it. You can order the standards you grew up with, or take a chance on a combination you wouldn't think to build at home. Either way, everything is made with the same fresh ingredients and the same attention to detail.
The core menu is anchored by five sandwiches, and it's a well-judged mix of the familiar and the inventive. The Halloumi Sambo is the house signature, built around savoury halloumi for anyone who likes their sandwich cheese-led and full of flavour. The Chicken and Roasted Capsicum pairs tender chicken with sweet roasted capsicum.
For traditionalists there's a proper BLT and a Classic Ham and Cheese — dependable, done-well versions of the standards that keep regulars coming back. And for something with a bit of crunch, the Poached Chicken and Peanut Slaw combines poached chicken with a nutty slaw for texture and bite.
The regular five aren't the whole story, either. The kitchen keeps things moving with specials, and the shop's Instagram feed is the running record — latest sandwiches, specials and behind-the-scenes moments, shared for anyone who wants a preview of what's coming out of the kitchen this week.
Coffee is the other half of the appeal. The Serious Sandwich brews fresh coffee and actively encourages the pairing: pick your favourite sandwich, add a fresh brew, and you've got what the shop calls the perfect meal. Whether you're after something hearty or something light, the sandwich-and-coffee combination is pitched as a flavour-packed everyday ritual — the kind of lunch you'll want on repeat.
There's a bigger idea behind the counter, too. The Serious Sandwich is committed to sustainability and to supporting local farmers, sourcing its ingredients responsibly. In the team's own words, behind every serious sandwich is a team serious about quality — working from sourcing the freshest ingredients through to crafting each sandwich, so that every bite reflects that commitment.
The shop keeps generous, consistent hours: Monday to Saturday from 9:30am to 5:00pm, and Sunday from 10:30am to 5:00pm. It's an easy stop for a working lunch, a coffee catch-up or a weekend wander through Sydenham.
Questions and catering enquiries are always welcome. Call 021 189 2915, send a message through the contact form on the website, or follow along on Instagram and Facebook to see the latest creations. Whether you're a BLT purist, a halloumi devotee or simply after a good sandwich and a fresh coffee in Christchurch, The Serious Sandwich makes a convincing case that the classics still win — especially when they're done this well.
