New York Deli

Hidden away beneath the glass-roofed Victorian arcades of Cardiff city centre, this much-loved deli has been building authentic American-style sandwiches since 1990. It has become something of a cult favourite, the kind of place office workers and shoppers slip into for lunch and then recommend to everyone they know. The reputation is well earned: it holds a glowing 4.6/5 from close to 600 reviews, with praise heaped on the sheer scale and freshness of what lands on the counter.

The signature here is the towering deli sandwich, stacked generously and made to order from quality fillings, with portions that genuinely test your appetite. There is also an unusually broad spread of vegan choices, making it a dependable stop for plant-based eaters who too often get short-changed elsewhere. Counter service is quick and friendly, and while there are a few seats, most people grab their parcel and head straight back out into the arcades. For honest, no-nonsense food and big portions, it remains one of the city centre's most reliable lunch spots.
