Cross the Sewickley Bridge from Coraopolis and the housing stock changes inside a mile. The borough side is terraced river-town blocks and a Fifth Avenue business district; the far bank is the Sewickley village, a walkable Beaver Street shopping district, and then Edgeworth, Osborne and the long wooded lanes of Sewickley Heights, which is one of the oldest concentrations of large houses in the Pittsburgh region. An anniversary order from the 15108 grid moves freely between the two, and the difference is entirely practical: on the borough side the driver can usually reach a front door from the sidewalk, and on the Heights side the front door can be several hundred feet up a private drive behind a gate, with a house number on a post and nothing else. Both are routine. What decides whether a surprise works is a mobile number on the order and a realistic time window, because an anniversary is the one occasion where arriving early is as wrong as arriving late — flowers that land at nine in the morning are sitting on a counter by the time the person they were meant to surprise gets home.
Where the dinner is matters more than where the flowers are. Couples on this grid go two directions on an anniversary. East, eleven miles down the Parkway West: Grandview Avenue on Mount Washington, where LeMont, Monterey Bay Fish Grotto and Altius all look back over the Point, usually reached by the Duquesne Incline; Station Square below it, where the Grand Concourse occupies the restored Pittsburgh & Lake Erie Railroad terminal — a nice piece of symmetry for a borough whose own historic P&LE station still stands; and the Strip District rooms like Gaucho Parrilla Argentina and Eleven. West and south, closer to home: Robinson's Settlers Ridge, the Moon Township restaurants along University Boulevard and the airport-corridor hotel dining rooms. In every one of those cases, do not send flowers to the restaurant. A restaurant will rarely hold an arrangement, has nowhere to put it during service, and hands you a vase to carry to your car at the end of the night. Send them to the house in the late afternoon so they are there when the coats come off, or to the hotel room if you are staying over. The flowers should be waiting somewhere you are going, not somewhere you are passing through.
The hotel version is common here for a reason most neighborhoods do not have: this grid is the Pittsburgh airport corridor, and the hotel cluster along Thorn Run Road Extension, Cherrington Parkway and University Boulevard carries Coraopolis and Moon Township addresses — the Marriott, the Sheraton, the Embassy Suites, the DoubleTree and the Hampton, Residence Inn and Courtyard properties around them, with the Hyatt Regency sitting inside the landside terminal at Pittsburgh International about eight miles west. Couples use these for anniversary nights when one of them is flying out the next morning, and out-of-town children book them for parents' milestone anniversaries. A hotel delivery has exactly two failure points. The first is the name: the front desk cannot accept an arrangement for a guest it has no reservation for, so give us the name the room is booked under, spelled as the reservation reads. The second is the hour: order for after the standard mid-afternoon check-in and the flowers go to the room; order for the morning and they sit behind the desk in a service corridor until housekeeping is clear. Downtown Pittsburgh's rooms are inside the radius too — the Omni William Penn on William Penn Place, the Fairmont on Market Street, the Kimpton Hotel Monaco, the Renaissance in the Fulton Building on Sixth Street, the Wyndham Grand on Commonwealth Place — and all of them work the same way.
