But if you are on foot, and peek though the fencing immediately beyond the heavy, stone flanks of Old Zion Lutheran Church (est. 1742), you spot an anomalous tableau - a jumble of trowels, claws, and watering apparatus visible through a lacy screen of peeling white birches.
This is the Osteria kitchen garden, Season II. And it is physical proof that, yes, broccoli rabe grows on North Broad; and that in raised beds in a graveled alley between the stained glass of Old Zion and the glassed-in extension of the restaurant's dining room so do boxes of reedy leeks and spring onions, and in planters, pine-scented lavender, dark Tuscan kale, and mint, accents and supplements to the kitchen's regular daily deliveries of herbs and produce.
The garden is not, on the other hand, very visible from the tables inside Osteria itself. So you may finish a meal of wood-grilled halibut with pale-green, fava bean crema, ramps, and house-made culatello, a Parma-style cold cut, and never know what lurks outside. Or have the slow-roasted lamb shoulder with artichokes, or Osteria's Margherita pizza, crisp and smoky, and be on your way oblivious that from the pavement itself, a garden has been coaxed.
But one evening, you may be informed of a special - the rich veal liver and pork terrine, for example, with pickled ramps, slivered radish, and house-grown spinach. And the words house-grown will trigger a question and perhaps an invitation out the back door to visit the unlikely, hidden spread - a skinny, 10-by-60-foot bonsai Ponderosa.
