Nice one. I love blackberries! For the drink try a splash on scotch (not a expensive one) next time.
It's the same in Sofia even in the parks there are lots of berries but people don't take them because they are afraid of pollution. To which i say fuck pollution I wanna eat some blackberries :D
Scotch sounds fun idea- I'm not a big fan of whiskey unless I tone it down and sweeten it- so I'm probably add some honey. And yes, I'd use a cheap whiskey.
