There is a web site about Coke vs. Pepsi and Yes I have walked out of a restaurant if they had Pepsi as their only soda offering, food would have to be extra special for me to choose a Pepsi restaurant although there are many that do, then I just drink water. If you’re a COKE fan DON’T visit Buffalo NY, the only place you could find a Coke there were chains that carry it like McDonalds, Carrabbas, Burger King, etc.
