I am a creature of habit. I take comfort in routine and familiar things. Thus, when I find something I like, for example a bar or restaurant, I frequent it over and over again. That's how I've become a regular at my favorite bar, located in San Francisco's North Beach district, 15 Romolo. It's nice to go someplace where everyone knows your name. Am I alone? Or do you have a special place you head to for drinks?
