How to say "Next time" in the past tense? I'm a bit confused on how to use the expression "The next time" in chinese.
I originally wrote
(after going to Kigali for the first he realized there were no ethiopian restaurants) 
于是， 他下次回基加利时， 就决定开这个餐厅。
But my friend told me that  a better way of saying it is 
他再次回基加利时
'下次' means in the future. '再次' is better here.
