Hmmmm.... It's hard to choose, but I'll say চকোলেট bars, because they come in different flavors, not just plain old chocolate. Plus, it comes in dark, milk, and white varieties. :D
I would definitely choose the চকোলেট Bar vs the চকোলেট Ice Cream . It's true that the চকোলেট Ice Cream May Be Yummy - but also আপনি might have to eat it a bit আরো quicker before it melts and be careful that আপনি don't stain yourself . Whereas for the চকোলেট Bar you're able to take your time while enjoying your snack !
