The crackers were just plain Saltines, which I like a lot, the onion definitely white and the cheese was cheddar. I think you got both white and yellow.
McSorleys is a very funky, very old Irish bar so this was no gourmet cheese plate. I also think they only serve beer, a light and a dark.
Oh right, and they only had one bathroom before that was fashionable. I suppose for many years no women were allowed and when they let us in they said, OK ladies, but you have to share the bathroom!
According to Wiki, McSorely’s was men only until the National Association of Gals forced them, kicking and screaming, to go co-Ed in 1970. The head was also co-Ed until 16 years later when they put in a second one.
