Imported Food - Snacks and Drinks

Hey guys, this is probably my 6th month in the city. That being said I haven't fully explored every corner out here, but I am on the lookout for stores or supermarkets that sell imported snacks and drinks like Prime or Flamin' Hot Cheetos for example. I moved from Hyderabad and we had Q Mart over there to satiate my imported snacks cravings. Do drop places that you know of down in the comments. Thank you!
