What experience are you expecting in a phone-free breakfast joint if you are there by yourself? Interupting other patrons meals to randomly talk to them? That sounds kind of like hell.
replyBoredom and being alone with your thoughts is not, as popularly believed, fatal.
replyOf course not, but its also not an exclusive experience you can only get at resturants.
replyAnd quite frankly noisey busy resturants are a subpar place to have that sort of experience. Most people who want to do that sort of thing go to a park or somewhere quiet with nature.
