This comment was posted on the site in the wrong place. I have added it here as I think it applies to this establishment, however Zest has two locations.  - Martin

I was taken to Zest by a girlfriend from Cockermouth who raved on about this fresh happening spot.  On entering i was very hopeful and to their credit the FRONT OF HOUSE STAFF were very good.   

After that I found it disappointing.  I ordered duck fillet with plum sauce which was atrocious.  I still feel angry that they could serve food that bad after the obvious effort that had managed to garner them the reputation that they have.  Was it a bad day for kids masqerading as chefs; the duck fillet had been precooked some time ago and it was badly dry.

I fully intend to go back and order the same again and if it is as bad as the last time; I will do myself justice and complain.
