Depends on the chocolate. I prefer European chocolate to
American chocolate. On the European side, I love Cadbury and
Toblerone.
On the American side, Reese's Peanut Butter Cups (a rareity in
Singapore, you don't see those on the shelves, although I have seen
a box in NTUC, near Marine Parade...HOOAH!), Hershey's Kisses, York
Peppermint Patties. Good stuff, but U.S. choco tends to be much
sweeter and less bitter than Euro chocs.
Like I said, it all depends on my mood at any given moment.
But, remember: there's no wrong way to eat a Reese's!
