"Once inside the Embassy there is inadequate seating, inadequate number of toilets and only snack/drinks slot machines which may or may not work. It was apparent when we went to London (May 2004) that 99.9% of applicants were students looking for Visas to study in America.

The timing for you was probably bad, my daughter was one of the students last summer (2005), not for studying (it is actually called a cultural exchange/study visa) to work in the US for the summer. Her appointment was around 11 and was all finished within a couple of hours, she was prepared and took food , drink and books with her, and it helped in that she is studying in London so the logistics were not quite so bad, it was only a short bus ride from her. For most in the same position as her they were unable to apply earlier as until they had their exam timetables didnt know when they would be able to fly over and start work.
If you don't have a particular time in travel in mind and can plan your application when it suite then you can probably get a quieter time.
