CC - Have you been to Sadlers Wells Theatre area? or the Angel Islington Market in the last 10 years?
These are better areas of London and have plenty of nice delis. I didn't say they were the majority. But they are areas of significance in Islington and the trend is towards gentrification.
To all posters - If people don't believe significant parts of North London have gentrified say since the 1990s they are walking around with blind folds on. I do know West London better and there many bookies shops, dodgy pubs, greasy spoon cafes have been replaced by estate agents, shops making bread for £5 a loaf, artisan meats, retro second hand furniture selling well above its original new price, Mediterrean deli, that to me is moving from working class to middle class to me. I can only report what I see changed over the last 25 years. In general I don't see the same change on Teesside I am afraid in fact some areas appear to have gone down hill. The average person in the street would know what Bosco meant by an Islington Deli and I believe the people on this board are intelligent enough to know to, but want an argument.
Ref Food non-tariff barriers will increase food prices e.g. quality checks - the EEC/EU have always (as a general policy) protected farmers with trade barriers from outside the EEC/EU which in general has kept prices higher with in the EU/EEC than they could be. The majority of politicians within the EEC/EU thought this was right for food security, food quality and to protect rural communities which form a higher percentage of National economies in many Member States than the UK and more importantly their vote can make a big difference in elections. The level of this protection has reduced in recent years - hence mass farmer protests within the EU about low and falling prices, and some EU rules that they say have significantly increased their costs.
