im not too far into it yet, but i did notice in the 4 panel shorts in the back of volume 1, the "cafe de Aerith" (which TP has as "cafe du Aerith") the drink Aerith is offering Leon is iced tea as apposed to lemonade and leon's complaining about too much sugar rather than salt. (does that count as notable?)
Tokyopop changed the drink. In the original Japanese version it was barley tea, but they made it lemonade. Yen Press has changed it back to barley tea.
