One of my worst meals ever, anywhere, was at one of those restaurants mentioned by poshglasgow.
The main course - lobster - was the smallest I've ever seen. It had been thawed out and so was mushy and tasteless.
Dessent was supposed to be a chocolate soufflé but it turned out to be a stale chocolate muffin served with a dollop of cream and surrounded by "artistic" splotches of raspberry sauce. Yuk!
It just goes to show that restaurant reviews are often too personal to be is any real use - a bit like describing guys as being handsome, I guess.
Mind you, it was a while ago so maybe they have lifted their game.
