Welcome, @chawlajyoti! Did you notice the comments in this thread by @amrita and @cathyfraser, who named some? Maybe this will help?

Amrita listed the following:
Old Abe Coffee Co
Royal Indian restaurant
Tonic
People’s food Co-op

Cathy added Hu Hot at Apache Mall

Maybe others will provide additional suggestions. 🙂

Stores like - Natural Grocers, Rice & Spice stock prepacked/easy to cook vegan options as well

If you get to Minneapolis - try Fig and Farrow. I was really impressed with their food, service and atmosphere (a little hippy). The small plates - cauliflower and brussell sprouts in particular - were excellent!
