We have Krystal here in the South, which makes the little square burgers also (I always liked them...ate quite a few of them when I was a teenager). Since I was a vegetarian for so long, I've just kind of lost my taste for fast food and don't see a real need to get back in the habit. Last time I went to Taco Bell (maybe 2 yrs. ago?) it was just nasty.
(I'm working a little seafood back into my diet now since I have had to give up some other things, so I can't say I'm "strictly" vegetarian anymore, just "mostly" vegetarian.)
