Kostadin Strezov is charged with the grievous bodily harm of Jamie Standing at the Angel bar in East Street, Shoreham, at around 11pm on Friday night (March 27).
He is also charged with possessing an offensive weapon.
Strezov, 22, of Queen's Place, is said to have stabbed Mr Standing in the back using a knife.
Police have recovered a knife, which is said to be up to 9in long.
Mr Standing's stab wounds caused his lung to collapse and damaged one of his kidneys.
He has had to have an operation, although it is thought he will survive.
At Worthing Magistrates' Court today (Monday, March 30), Strezov appeared in custody and spoke only to confirm his name and address.
He did not enter a plea.
His solicitor, Brian Shaw, applied for bail for Strezov, but this was denied by magistrates.
The defendant will remain in custody until June 25, when he will appear at Chichester Crown Court.
