Satnam Singh Blugher was found with stab wounds at Tony’s Diner on the A458 Welshpool to Shrewsbury road at Halfway House, on June 26.
Mr Blugher had run the diner for 15 years.
Belkar Singh, 58, of Booth Street, Birmingham, denied murdering Mr Blugher when he appeared at Stafford Crown Court yesterday. He was remanded in custody and is due to stand trial at Stafford Crown Court on December 11.
A murder investigation was launched after Mr Blugher was found with serious injuries at the diner.
He was discovered at the diner by paramedics following a 999 call.
Police were called and launched a murder inquiry.
Following his death, Bal Blugher, the daughter of Mr Blugher’s son Harry, said: “Because he had the business for 15 years, he saw lots of customers and knows people from across the West Midlands and Wales.
“We want as many people to be able to come and say their goodbyes to him.”
Mrs Blugher said that anyone who knew her father-in-law and wished to attend would be asked to wear black and bring a headscarf for the service at the temple.
She said: “We would also like to thank the community for their support at this difficult time. Everyone has been very supportive.”
