The Quarter
Which includes little stonegate & grape lane, houses several nice bars such as pivo, stonegate yard, bobo lobo, slug and lettuce chain bar, 1331, wilde's & oscar's to name but a few. tends to be slightly more chilled out but more expensive than other areas. still rowdy on a weekend but more relaxed during the week where salsa lessons take place in a couple of the bars. the area is sometimes referred to as the 'latin quarter' due to the nature of some of the bars and restaurants.
An excellent map of York bars, complete with reviews, is available here: (http://maps.google.co.uk/...)

The Minster Inn
confusingly not that near the Minster at all. As it's slightly off the tourist trail, most of the people in there are local regulars, but you're guaranteed a warm welcome, some local colour and an excellent pint.
