The problem with most people who say, "I love coffee" is that, often, they don't! What I mean is that they really ought to say, "I love coffee drinks". If you're drinking capuccino or latte, it probably doesn't matter which of the above (over-priced) outlets you go to - it's all a matter of personal preference. People who really love coffee look for places that offer a good range of beans (Colombian, Brazilian, Javan, whatever) and choose whatever suits their taste or their mood. Despite the growth of the chains listed above, it's still the small independent shops that frequently offer the best coffee (and often at far more reasonable prices).
