Legal Question in Consumer Law in Pennsylvania

Re: Restaurnat Complaints and Refunds

Generally, no. If the menu says, "satisfaction guaranteed," then maybe.

Basically, the contract at a restaurant is that you agree to pay for the meal you order. If you're disappointed, you might have grounds to sue for a refund on grounds of failure of consideration, or implied warranty of some kind, but that doesn't give a right of self-help by refusing to pay.

Usually if you tell the manager about the problem, they'll offer something to try to make it good.

Similarly, most retail stores have generous return policies, but that's a matter of customer relations, not legal obligation.
