Could be maybe a meyer lemon. Looks like it has leaf shine on the leaves, or are they naturally shiny?
My vote is for coffee too (either that or gardenia but I doubt that). If it was a lemon, the new leaves would be a bronze colour.
Yep, it could very well be a coffee plant. It's was hard to tell for sure.The leaves look similar to my meyer lemon as well.
I am opting for Gardinia http://gardens.guppystorm.com/?cat=82 Site below has some young coffee plants www.daleysfruit.com.au/blog/2007_01_01_Fruit-... Liz
