This review is based only on their veggie burger meal. If you are vegetarian (vegan), your only possible non-egg and non-dairy menu option at Swiss Chalet is their veggie burger, but be sure to specifically mention your preferences or you might find your veggie burger topped with cheese and mayo :)
The veggie burger itself is kind of dry but the portion is alright, usually comes with a side of fries but you can ask for salad.
You may not be happy with the dry texture and bland taste but they do offer Tabasco sauce and I'm always thankful and appreciative to have AT LEAST one vegan option on the menu!
