London's Iranian food scene has a spicy new talking point: the sosis bandari sandwich, a Gulf-coast street-food classic of spiced sausage slow-cooked with tomato, onion and chilli heat, now landing in the city thanks to the team behind Berenjak and their sandwich-focused offshoot Mardys.
If you know Berenjak, you know the drill — charred kebabs, saffron rice and endless fresh bread out of the tanoor, all inspired by the old-school kabab houses of Tehran. The group's more casual side, Mardys, leans into Persian street snacks, and the sosis bandari fits that brief perfectly. It's a sandwich with real pedigree: bandari refers to Bandar Abbas, the southern port city where Iranian cooking picks up bold, slightly fiery flavours from trade routes across the Gulf. The sausage is simmered down until it's deeply savoury, spooned into bread, and usually finished with pickles or hot sauce.
The appeal for hungry Londoners is obvious. Persian cuisine has had a proper moment in the capital over the past few years, but most of the attention goes to grills and stews. Sandwiches like this are the everyday eating of Iran — quick, cheap in spirit and packed with flavour — and they're far rarer on menus here. Mardys and Berenjak putting it front and centre gives the city a taste of a different side of Iranian food culture, the kind you'd grab standing at a counter in a bazaar rather than sit down to for a long dinner.
Practicalities: Berenjak's original site sits in Soho, with an additional spot at Borough Yards near London Bridge, while Mardys operates as the group's quicker, more affordable street-food concept. Expect the sandwich-eating experience to be casual — order, eat, move on — which makes it an easy add-on to a day out in central London rather than a booked-in-advance occasion. Prices should sit well below the typical Soho dinner, in line with the snack-forward format.
Why it matters for travellers: if you're visiting London and want something beyond the usual food-tour stops, this is a low-risk, high-reward pick. It pairs neatly with existing plans — Soho shopping or a Borough Market wander — and it introduces a dish most visitors will never have tried. Food-focused travellers, curious omnivores and anyone chasing chilli heat should have it on the list. Vegetarians should check the menu on the day, as sosis bandari is a sausage dish at heart, though Persian spreads generally offer plenty of sides like aash, olives, pickles and breads to build a meal around.
The wider takeaway is that London's dining scene keeps going deeper into regional dishes rather than just national ones. A port-city sandwich from southern Iran appearing in the capital is exactly that trend in action — and it means there's a genuinely new flavour to seek out on your next trip to town.
