The best way to find a great restaurant/bar/etc is by following the local crowds...guidebooks are good for info on sites and background but when it comes to food and drink local popularity is always the true expert.
Always have a sense of humor about things, especially the unexpected.
Meet people, they're easily as interesting as any tourist site you'll see. At the same time, don't be too trusting of what people tell you especially if you didn't ask them for help or directions...most people are cool but some will take advantage of you, trick you, straight up lie to you so a healthy bit of caution goes a long way. Western Europe doesn't have this nearly as much as elsewhere but still it's a good habit.
Be careful about ordering items or entering clubs where the price/cover isn't clearly listed or stated...it's rare but some establishments do charge tourists through the nose because of it.
Watch your valuables, pickpockets are around and they will ruin your day/week/trip if you give them the chance.
