Regardless of the legality, if you know carrying guns in public--openly--is going to make certain people uncomfortable, maybe you should put it in your purse or your jacket or something?
Unlike open carry, concealed carry is against the law unless otherwise permitted by the state to do so. The permit must be obtained by the local Sheriff or metropolitan equivalent, costs 19 dollars and expires after five years. Pennsylvania is a "shall-issue" state, meaning that if you're lawfully able to own a handgun, the state must give you a concealed carry permit.
Maybe you don't need to bring your handgun to dinner with little Timmy the 6 year old at all?
Maybe I don't need to take it to the mall.

Maybe I don't need to take it to campus.

Maybe I don't need to take it to a restaurant.

Then again, maybe I do. Better to have one and not need it than need it and not have one.
I'm one of those wacky liberals that thinks people should be able to own and carry guns, but I also find it a little odd that some people feel compelled to carry their guns--openly--to a family dinner out? And then cry a freakin river when it causes a ruckus... what were you expecting?
I sympathize with what you're saying, but until people are allowed to carry concealed weapons without and guff from the government about it, then people are going to exercise those few legal options they have left to protect themselves. The operators of the restaurant did not feel particularly worried about it. It was other patrons that became worried. They had the option to notify the operators of the business and to leave.
If you were these people and I came up to you and asked you to kindly put your weapons away because it was scaring my kids, what would you say? I am genuinely curious. That's probably what I would have done had the situation arose rather than calling the cops.
At the moment, I'd say, "Sorry, but it against the law to conceal a weapon in Pennsylvania without a concealed carry permit. I don't have one. If I 'put the weapon away', then I'd be breaking the law. But, if you feel that strongly about it, I'll give you the URL to a website where you can write your congressmen and other state leaders to allow the carrying of concealed weapons without going through the arduous task of obtaining a permit."
If I had a permit (and soon I will), I'd already have the weapon concealed.
