Yeah...the good old days...
3 "all-you-can-eat" cafeterias, one at Mahoney-Pearson, one at Hecht-Stanford, one in the UC (Hurricane Cafeteria, it was "supposed to be" for Eaton)
1 Eye cafeteria, essentially a Burger King (no joke)
1 Rathskellar, just bar food
1 Ibis cafeteria, just an "a la carte" version of the others, though they had a sandwich area and a couple of other things, it was a forerunner of the food court
1 Force Five convenience store
1 Law School "Subway", they made the sandwiches at the Riviera Subway and brought them over to a refrigerator, later they had a "real" Subway
That was it. Those were our choices in the 1980s and early 90s. No food carts or food trucks, no other choices but to go off-campus.
