Staff at a pizza restaurant in Gloucester were threatened with what was believed to be a handgun as they were cashing-up.
Police were called to Pizza Hut, in Arthur Street, in the early hours of Sunday following reports of the robbery.
A Gloucestershire Police spokesman said the men escaped with a "small quantity" of cash.
Three men, aged 18, 19 and 21, were arrested shortly afterwards.
The trio remain in custody helping police with their inquiries.
No-one was injured during the incident.
"Anyone who witnessed the robbery, which happened shortly after midnight, is asked to contact police," the force spokesman added.
Arthur Street remains cordoned-off while the investigation continues.
