TRICK OR TREAT?

This Halloween, HI ELEVEN is dressing up for the occasion and so is the buffet. Expect international favourites with a wicked little twist, from Spooky Ghost Caprese Salad and Dark Night Loaf to Beef Wellington “Mummy Roast”, grilled river prawns and seafood on ice.
Things get even more suspicious at dessert. Meet Devil’s Eye, Black Magic, Witch Cupcakes, Spider Chocolate Black Forest and Red & Charcoal Churros, alongside plenty of sweet treats worth saving room for.
No tricks here. Just a seriously good feast with a spooky side.
