Fresno is an extremely diverse city with virtually every culture and religion represented. It has one of the largest Sikh & Punjabi populations in the country with over 50K people. There are over 20K Muslims in the city, and a large population of practicing Hindu & Buddhist residents. While Christianity & Catholic religions remains the majority of the population it is far from the only religious services offered.
Fresno has a ton of very good international markets for authentic groceries. The International Market is the #1 place to go, but I have heard very good things about all of them.
