An important question - How do I know what restaurant food is vegan?

I have found the following valuable in assuring that my choice to enjoy a plant-based diet can be, and is being, accommodated by restaurants that I visit:

• Basic research prior to visiting the restaurant. Google “vegan food at (name of the restaurant)”. The results often identify what menu options will work and those which will not.
• Reverse research. Look at the restaurant’s menu online, pick out a couple of potential choice and then research those choices to determine if the items’ general ingredients are vegan. If the items have the potential to include an animal product, keep the option in mind and ask about it when you reach the restaurant. For example “Does your marinara sauce contain cheese?”
• Ask the restaurant staff. I have found that most folks are very happy to help when I ask about vegan options. On several occasions I have asked about vegan options from the menu and when none were available the server says “I will ask the cook to come up with something for you”.
• Lastly, search Amazon for books about “Vegan food in restaurants” I find many are available at this link: Vegan food in restaurants

Having enjoyed several decades of plant-based eating, during which I have dined at many restaurants, I can count the less-than-optimal experiences on one hand. The vast majority of experiences have included wonderfully helpful people and delicious plant-based meals.
