A "cocktail bar" should offer great tasting, well-balanced cocktails made using quality ingredients and fresh juices but as the style of bars vary enormously...
There are lots of bars serving cocktails but few decent cocktail bars where I live. I love going to a bar where you know the bar tender really understands the craft of cocktail making. I was in a bar in Newcastle last week when I asked for a classic martini, the young lady who made it for me was keen to hear my views because it was only the second one she had ever made, it was very, very good and we had a great discussion about what makes a perfect martini. I’ve learned so much from using Difford’s Guide!
