corporate dining rooms/cafeterias

friends and i are fighting boredom by eating at each others' workplace cafeterias, and we were wondering if there are any notable places we should try and hit.

and yes, sometimes trying to get into them (without knowing somebody who works at that particular establishment) is much more fun than the dining. . .

fyi, i work at hsbc on 40th/5th, and we have restaurant associates prepare our cafeteria fare (not bad--great cheesy herby clam chowder..) and have a team of chefs prepare food upstairs in our dining rooms. (good, but the same menu for 8 years. . .)

anyway, any suggestions?
