"There's quite a difference between places that serve Garden Burgers and places that serve seitan "chicken"."

What would that difference be? I wonder because places like the Mad River Bytes and Mango Thai and apparently hundreds of other restaurants offer (and presumably serve) seitan chicken, veggie burgers and genuine meat all from the same menu.

I dine out quite a bit. It is not at all unusual for places which one would think of as 'conventional' restaurants to offer vegetarian specialties alongside 'conventional' fare. I could not name any local eateries because I do not care for vegetarian fare (remember Cain & Abel - apparently vegetarian fare did not work for Christian god either).

I am a native English speaker, although you might not know from reading my writing. I write as well as I can - sometimes.
