You're thinking of the Pig & Calf Lunch...traces of the old signage are still visible today, and there's a nice New Mexico Historic Landmark sign that's been put up in the last few years.
Hoyt's Dinner Bell was waaay before my time, but my mom remembered it as one of Albuquerque's few "fine dining" options when she was a girl in the 50s. I think you may be right about its location - the impression I had from her was that it was in East Nob Hill somewhere in the vicinity of Solano or Aliso.
Yep - not much for "Hoyt's Dinner Bell" turns up on the internet except this old postcard, but fortunately it has an address...it's at Central and Aliso and there's a laundromat on the site today.
Anyone remember the roller rink on east Central? It was a popular place for servicemen during WW2. Lots of fights. The sides opened up for cooling during the warmer months and you could see the skaters doing their thing. South side of Central at about Espanola.
