If Peter Piper picked a peck of pickled peppers, where’s the peck of pickled peppers Peter Piper picked? Who cares? But we’re pickled tink, er, tickled pink over the reopening of Pickles, tomorrow on the edge of Jackson Square. The artisanal diner got an extensive renovation (polka-dot booths, cement tabletops, fireplace, and looks-like-wood tile floors) and menu makeover (all-American classics from crafty new chef Matthew Kerley, a Myth alum). Dinner rolls out in a month or so. For now, go for lunch on the heated patio with a retractable roof (great Transamerica views) — pots of pickles, sliders, mini corn dogs, hearty salads, and beer-battered onion rings. Save room for a frozen custard sundae with mix-ins like crumbled toffee served with an edible chocolate spoon. They just roll on the tongue. Pickles, 42 Columbus Avenue, between Jackson and Washington Streets (415-421-2540).
