During Lent they serve a pepper and egg sandwich. There are salads that can be made without meat or cheese. Not a lot of vegetarian options though unless you're into side items.

There is a salad section in the restaurant, not sure how well it hews vegetarian and/or vegan.
I'm not sure I think you can search it online and find all those answers on their web page..
