Between Jūrmala and Kolka on the gulf coast, eating opportunities dwindle right along with the population density, although you're never from a basic supermarket. Be sure to save time for a stop in Ragaciems, where there's a pod of vendors right by the P128. Several sell myriad varieties of smoked fish while others specialise in tasty Latvian fare such as pickles, grilled meats and rye bread. It's truly picnic heaven.
