The four-finger bar smelt convincingly of coffee. The chocolate was of standard Nestle quality (I much prefer both Mars' and Cadbury's milk chocolate). The coffee came through as a mild flavouring, certainly earning its status as mocha rather than espresso, which gave it a rather comforting element. The wafers were perfectly crisp, but the ratio of chocolate to wafer was rather stingy- but maybe that's only my chocoholic opinion!
Overall, this is a pleasant bar, but I wouldn't choose it regularly over a more chocolatey product. I just wish there were more true coffee chocolate bars on the market!
