According to the Random House Second Edition Unabridged, a coffee shop is "a small, usually inexpensive restaurant where refreshments and light meals are served." According to us, a coffee shop is also a place where the waitress remembers how you like your eggs the second time you come in; regulars drop by to schmooze, eat the blue-plate special, and read the paper; and nobody rushes the guy at the counter nursing his second cup of java. The Nob Hill Grille is such an oasis. A warm and friendly neighborhood vibe prevails as a cheerful waitstaff keeps the joint humming and skilled countermen cook up breakfasts, burgers, and daily specials of unusually high quality. The club sandwich, for instance, is packed with chunks of lush avocado and moist chicken fresh from the grill. The Cobb salad overflows with smoky bacon, freshly roasted turkey, a marvelous cumin-scented dressing, and a bushel of spring greens. Or try one of the rich, spicy curries, a house specialty (the lamb variety is especially tasty). For dessert there are sundaes, floats, and shakes -- as well as an exemplary apple pie, of course, that's very good with that second cup of joe.
