Charcoal broiled burgers — yum! Focusing on the new Kuro(Black) Diamond Burger(limited menu item item from September 18, 2014). It’s basically a black Whopper with cheese. Differences are: Black bun, black sauce, black cheese. And tastewise, it had less charcoal flavor than usual but the sauce had good aromas of soy sauce, slow-cooked onions and spices. The sauce was a bit in the salty side, however. Ordered a side of fries(M). Deep fried consistency was OK, slightly on the overdone side but the cuts are thicker than at the«other» hamburger chain, plus skins are left on. Overall, a slightly different flavor experience compared to the usual Whopper. Not bad, but not great — it would probably be better by doubling up on the meat patty and cheese. Worth a try with the drink special(30%) off normal individually purchased prices.
