I'm not aware of any Hilton properties that comp a full breakfast for elites who are given lounge access. Lounge breakfasts are generally skimpy, but there are exceptions. One of my regular Hiltons (Beachwood, east side of CLE) used to serve quiche, but only on Fridays. International properties are more generous at breakfast than the US Hiltons I'm familiar with. I never thought of the breakfast as a dealbreaker. If I want to be stuffed before I leave in the morning, I stay at an Embassy Suites.
