Not an eatery per se but a fresh produce grocery market about a click south of Duncan right on the highway on your right as you approach the town from the south.
While the market produce is fantastic, and includes a 40% off after 4pm discounted produce plan, this shout out is for the attached deli: wow to the food and wow to the prices. Everything is made fresh to order and the prices are crazy reasonable. It seats maybe 10-12 customers (its mostly take out but you can order and grab one of the few seats/tables). The cost for a breakfast that will fill even me up was $9.
Yesterday while scouting the Cowichan River for an upcoming fishing weekend we stopped in for a late afternoon bite. Ordered a very filling supremely good tasting Hungarian salami with lettuce, cheese, mayo and mustard sandwich on marbled rye bread (right out of the oven), a huge crunchy garlic dill pickle (gotta have a good crunch!), a medium bag of Old Dutch cheese nacho chips and large local bottled water; that was all of $11. Huge recommend for both the market and the deli especially.....
