It seems that some restaurants put a series of optional extras on your espresso saucer: cinammon, lime, cane sugar lumps etc. I was very impressed and being an open minded sort of guy I thought I´d throw everything in and see what happens.. it definitely hits you a little harder than your average coffee but in future I think I´ll save the limes for the Caipirinhas!!!
ps. Has anyone seen the coffee and lime combo before?
pps. Be warned this is what happens to Brazilians when they mix cachaça, coffee, sugar and lime
