An account about breakfast in Barnum's:
Charles Weld (1813-1869) was an Englishman who visited the huge hotel in 1855 and while he could not secure a room was able to procure a bath and breakfast.
"Barnum's Hotel, for which we were charged a dollar each. Here, however, we plunged into even greater chaos. The large hall of this large hotel was thronged by hundreds of people, striving to inscribe their names in the bar-book. Finding that every room in the house was already occupied, I took no part in this struggle; preferring rather the luxury of a warm bath, which was particularly refreshing after the wretched night I had spent. This, and an excellent breakfast, to which I sat down in company with about 500 persons, gave me renewed strength for sight-seeing duties.
The resources of American hotels are really wonderful. Sleeping accommodation has its limits, but the wealth of the culinary department seems to be boundless. No accession of visitors, be they ever so numerous, exhausts the supplies.
