The users claimed that by having the 'Halal' option, Zomato is associating religion to food.
Reacting to this, Zomato said in a letter the tag appeared on their site or app because people had asked for it before and that is how the website is programmed.
"We provide this information, so that you, as a customer, can make an informed choice about whether you want to eat Halal meat, or not. As an aggregator, it's imperative that we showcase all the various facets that a restaurant would like us to display to its potential customers," the company tweeted.
"Bye bye Zomato, you lost one precious customer, many more to come. Don't support one side if you can't resolve the issue. #ZomatoUninstalled," tweeted one user.
Many uninstalled Uber Eats' app too and tweeted #BoycottUberEats for supporting Zomato.
One user wrote: "Can @ZomatoIN tell me what's wrong in fearing food delivered by a Muslim in times when Muslims jingoistically follow jihad to the extent of poisoning Hindu food? and if food does not have a religion why do you care to replace Halal meat with a non-Halal one?@ThePlacardGuy #Zomato."
The controversy began on Tuesday when a Zomato customer tweeted: Just cancelled an order on @ZomatoIN they allocated a non-Hindu rider for my food they said they can't change rider and can't refund on cancellation. I said you can't force me to take a delivery. I don't want don't refund just cancel."
In response, the official Twitter handle of Zomato tweeted: "Food doesn't have a religion. It is a religion".
