It is amazing!!!! Our three kids (13, 11, 10) absolutely love it. And - you can get it as a side so you don't have to get the turkey wrap. Although that is good, too.
My DD loves the corn chowder and orders every time we eat at Tusker House. As for being vegetarian, I can't really say. My DD is a vegetarian and we usually ask at each restaurant as to the soup's base. In most of the cases the soup comes from a chicken stock base. This includes many of the soups you would think of being vegetarian such as tomato (Plaza restaurant). I keep forgetting to ask at Tusker House about the chowder. I'll have to do that on our next visit.
