We come to Pei Wei almost every Sunday. Today was the first time the service was unsatisfactory. I would excuse this if they were busy but there were only about five tables occupied. Almost all of the unoccupied tables were unclean forcing us to sit on the patio. The unclean tables remained uncleaned for easily twenty five minutes. Not to mention the food took just as long to get out to us as it did for them to clean the dirty tables.
