Either in a restaurant or available for purchase would be fine. And I wouldn't limit it to pickled cucumbers; I love all things pickled. I love the pickles at both Canter's and Langer's. La Espagnola's saturday paella comes with a delicious side of pickled veggies and I think I remember also having some housemade pickled veggies at Fig as well. And Surfa's carries a great line of pickled stuff that includes green beans, okra and tomatillos. Where else?
