Rhea’s Market & Deli is two blocks from Dolores Park in the Mission, making the corner store a prime candidate for pre-picnic shopping sprees. The grocery section has everything from chips and bottles of wine to an impressive assortment of Milano cookies. But you’re here for the sandwiches. They’re customizable, loaded with fresh toppings, and hefty enough to significantly weigh down your tote bag. We like to leave fate in the hands of the sandwich professionals and stick with one of the many pre-determined combinations, like the “Diamond Hts” with turkey, bacon, BBQ sauce, and honey dijon on toasted dutch crunch, or the “Three Lil’ Pigs” stuffed generously with ham, salami, and bacon. Fill out an order form and people watch from one of the bar stools by the front window while you wait.
