(Portland, OR) -- Portland ranks number one among the top 20 cities in the U.S. for vegans and vegetarians. The WalletHub study compared 100 cities using 17 metrics, including the cost of groceries for vegetarians and the availability of meatless options in restaurants. Portland got the top spot thanks in part to its organic farms, community gardens, farmers' markets, and vegetable nurseries. The report was released ahead of World Vegan Day on November 1st.
