The largest table in PG on both QE & QV is usually a mix of solo travellers and couples who always look like they are having a whale of a time, saying that we have met solo travellers in PG who prefer to eat alone, so you are not forced to mix if you don't want to. As already stated the QE & QV Courtyard, situated between the PG & QG restaurants is for alfresco dining.
