Pizza is one of the most popular dishes in America and restaurants across the country are offering deals on Friday, Sept. 20 in honor of National Pepperoni Pizza Day.

According to a 2021 YouGov poll of the most liked and disliked pizza toppings in America, pepperoni is the country's favorite topping, with a whopping 64% of Americans saying they like it.

Other popular toppings include sausage, mushrooms, extra cheese, and onions, according to the YouGov poll of more than 6,000 U.S. adults. As for the most disliked toppings, anchovies were the runaway winner (or loser?) of that category, with 61% of respondents saying they dislike the topping on their pizza.

Here's where you can get deals and discounts on pepperoni pizza this Friday and upcoming weekend.
