I had a Hotel Chocolate Rocky Road to Caramello egg and personally I didn't find it all that spectacular, but it might have been because a) I waited about 3 months to try it and b)my student house gets horribly hot and I think has a tendency to sap chocolate of any flavour. I can't seem to find anywhere to store it! I'll see if I can get to a branch when I get back to the Midlands and a normal house though.
Thanks for the Lidl tip though: I'd totally forgotten about them, they're often brilliant for interesting continental chocolate and that kind of thing. Is their white chocolate bar very nice?
Out of interest, what do people think about the changing of Cadbury Heroes Dream and Crunchie for Bourneville and Eclairs? Myself, I really enjoy the Dream and especially Crunchie, but I do understand sometimes one desires dark chocolate. Its rather ironic considering Bourneville was actually removed from Roses though.
