San Diego, California is an excellent place to launch a restaurants business. With a population of 1.4M and ~150K businesses, San Diego offers a robust market. Restaurants face constant liability exposure from food safety issues, customer injuries, employee disputes, and liquor liability. An LLC ensures that a single lawsuit does not put your personal home, car, and savings at risk. Most landlords and investors also require a formal business entity before signing a commercial lease or funding a restaurant venture.
