Dosirak Kitchen in Seoul takes custom group lunchbox orders for companies, schools, and weddings. It offers a two-tier premium ssambap lunchbox and guest anju lunchboxes, and prints company logos and brand colors on the packaging. Orders repeatedly arrive earlier than the requested time on the event day, and staff quickly apply changes in headcount and requests. The kitchen is set up for events with multiple attendees rather than individual meals, so it may not suit small orders.
