Sonoma Restaurant and Wine Bar made for a fine setting for the Organization for International Investment’s annual Capitol Hill Insourcing Reception.

The staffers and business representatives who attended the Thursday night affair had the second floor lounge Sonoma Restaurant and Wine Bar largely to themselves.

The RSVP list broke down heavily on the side of congressional staffers, followed closely by dues-paying OFII members. Of the eight lawmakers on the list, only Reps. Charlie Dent, R-Pa., and Bill Foster, D-Ill., made it to the event — a bipartisan, if modest, showing.

Reception attendee Carol Danko, press secretary for New York Republican Rep. Michael G. Grimm, told HOH that between votes and allergies, her boss was tied up. Meanwhile, a staffer for the absent Sen. Mark S. Kirk, R-Ill., topped off a fresh glass of white wine with the dregs of an old one between quips with her colleagues.

The OFII is a nonprofit business association that lobbies lawmakers on behalf of the U.S. operations of foreign companies that join its ranks. The organization provided every attendee at Thursday night’s gathering with a beer glass and mini bottle of spirits procured by Diageo, the social lubricants giant.

In addition to the party favor, an open bar kept the spirits flowing and a flotilla of heavy hors d’oeuvres, including grilled shrimp and mini crab cakes, filled bellies.

The star of the evening was Jonathan R. Otto, public affairs specialist for automotive giant Honda’s government relations office. Otto won the raffle prize, a weekend stay with deluxe accommodations at the Foggy Bottom Ritz-Carlton.
