This place doesn't have much by way of vegan options at all - but they do have a really good vegetable soup. I was really surprised by how much I liked it. It's not on the menu, they only list "soup of the day", but our server told us they do serve the same soups everyday. I was also able to get some steamed broccoli and lemon wedges to squeeze on it - which isn't anything remarkable, but it did taste good. Plus, my meal was pretty cheap compared to everyone else's in my party, and it filled me up.
I would give Chili's a higher rating if they had more than two options - the staff was extremely helpful in answering questions, and even brought me a printout of the ingredients in the soup. They said they are happy to do that for any item on the menu.
