I was first introduced to this plate of sweetness by Ana, but I finally managed to try it in February 2014. In all honesty, I would say that for RM6+, it's not quite worth it as the slice given is actually really small.
Then again, once you've started eating, it's too sweet that you probably wouldn't even finish it. 👀
My advice is since Calanthe Art Cafe is famous for their coffee, you should order a cup of coffee to go with a place of this caramel slice. Maybe then that would do the trick. Who knows?
