Dear me, my very first post is about booze! When I saw this topic I couldn't resist- last night I had a shiso G+T. Easily available here in Japan, I'm not so sure about other parts of the world. Adds a really pleasant herbal backnote to the drink. No actual leaf in your glass, instead they infuse the gin with 10 leaves or so. I had this one with lime, but here yuzu is also really popular. Touch on the sweet side for me though.
