The canteen inside the Berlin campus of David Chipperfield Architects in Mitte opens at lunch to anyone walking in, not just the in-house desks.

Joachimstraße, a courtyard between exposed concrete and narrow window bands — long counter, clean lines. The card stays small and rotates daily: a soup, a salad and a few mains. Always a vegetarian option, meat one day or fish another. Modern, vegetable-led, no fine-dining pose. The bread from a Berlin bakery travels through Mitte quickly. At midday the room fills with the Joachimstraße crowd from architecture offices and studios.
