Big Disappointments

I'm doing a big of a bucket-list run-through and trying things I've never done before.

The last two have been real let-downs - I tried black pudding - never liked the thought of it - and it was gross - like a great big greasy scab.

The other is something that my brother-in-law has been promoting for years - a McFish Fillet burger.   It's the only thing he eats from McD.

Had one yesterday - it's just a big fish finger with practically no flavour.   Watery and bland.    It rates as a great big 'meh'.

What have you done recently that was not as described?
