Aside from "gourmand," consider "bon vivant," "food epicurean," and "hearty eater."
bon vivant: (from French) a person who enjoys going out with friends and eating good food and drinking good wine.
to be compared with:
hedonist: a person whose life is devoted to the pursuit of pleasure and self-gratification.
bon viveur: a person who lives high and well; man-about-town.
However, "gourmet" and "gastronome" don't necessarily imply a hedonistic behavior to my French ear, but rather some sophisticated knowledge about high quality (often expensive) food and wines, coupled with the enjoyment of choosing, eating and drinking them.
