Part 3. Exercise
I really need to learn how to complain. Sitting eating something badly cooked, mumbling 'it's fine, thanks' when asked, and then coming on here to moan is less than ideal, I know...

But anyway, here I am. I really had high hopes for The Saint. It had been recommended by a friend, the web site and menu looked lovely, and the restaurant itself is attractive - dark wood, candles, and an open fire. When Jason suggested we go there, I was excited.

The menu is limited at lunchtime to soup, omelettes, eggs benedict and a couple of open sandwiches. You'd think that would make it easy to get things right. But my mushroom and blue cheese omelette was a masterclass in how not to do it. It was overcooked to the point where the outside was blackened, there was barely any cheese or mushroom, and it came with a pile of dry rocket leaves that were probably fresh last Tuesday.

Being me, I chewed my way through it, paid, and then whinged once we got outside - and bought a cheese roll in Kay's bar when we stopped in for a pint on the way home.
Answer:
NEGATIVE
