Gin Punch: 3 slices of orange, 1/4 lemon, 1 slice pineapple, 1 slice apple(all peeled of course), 4cl passion-fruit liquor, 4cl gin, 2cl grenadine syrup blend it with a handful of ice, and add some OJ as fill-up.
Everybody loves it: it's fruity, it's rich, it's stronger than the average long-drink, very drinkable. It's one of my signature "surprise me" drinks. Every guest in the bar appreciates the half ton of fresh fruits, and the extra effort you put in the drink. Only downside: it's quite slow(unless you have peeled stuff) and a bit messy, so not for a busy bar.
