TGI Fridays does not list the prices of most menu items online until you are ready to order. In fact, finding the price for a simple soft drink like a Coke is more difficult than finding actual copycat recipes for some of the chain's top-selling entrees. A bottled Coke averages around $2.30 but may vary by location. Fountain drinks may also vary by size and by location. You may have heard of the man who sued TGI Fridays after being charged for a drink that he felt was vastly overpriced. He said that had he known beforehand how much the drink cost, he would have skipped it.
