    "For the most part (unless you live in West Cotati) everything is very walkable.. actually even if you live in West Cotati there is a tunnel under the freeway.. So walk everywhere and buses too. Great nite life yet quiet and small townish- except at rush hour the main roads are packed! "

  • S r.
    "Sonoma State is a big part of the economy/community here so there's several bars and a handful of fast food restaurants. the city-Cotati- is destitute financially so be aware of getting parking tickets for ridiculous minor infractions even on a quiet residential street. There are very strict dog/leash laws enforced and you will get ticketed for that too if not careful. Dogs are not even allowed on a leash in the park downtown at farmers market. "
