To work in a gastronomic field in the dream (as a chef, a waiter etc.) is to get a nice surprise from your lover, or from an admirer if you are single.
To get absorbed by gastronomic pleasures is to experience pleasure in real life. It will not bring you money, but you are not going to spend anything either.
To go shopping in the grocery store is to make big purchases, maybe for work.
To see plenty of food you are not buying indicates that you have several admirers.
