Doris' Super Bar appears to have been a short-lived bar. It was apparently opened in 1975 or 1976, first appearing in the August 1976 GLIB guide as well as Bob Damron national guides for 1977 and 1978 (it did not yet appear in the 1976 version). But in August 1977 issue of GPU News an ad appeared for Lambda Lounge which reads "formerly Doris' Super Bar".

Any further information about either of these businesses is welcome.
