I have done another Lindt bar and a few other of their products (search it on my blog) and this time I'm doing the double milk bar.
This bar is a lot like a Kinder Egg but the chocolate of course is different. It just tastes faint of kinder but it's not a bad bar. I don't think I'd buy it again but I'd eat it again if offered, I rate it 3.5/5.
Update: it's been a few years since this review and I did continue to buy this bar and I love it, it's delicious. The more I ate the more I liked it, it's not as good as Kinder but it's the next best thing, this is one of my favourite chocolate bars right now and I rate it 4/5.
