I tried posting about this yesterday, but I must not have hit submit or something.
We were dining out for lunch on Monday before we went to a movie and I saw they had mushroom bisque on the menu. Looked like a seasonal option. I asked to see it and it wasn't creamy at all, it was rich and looked full of mushroomy goodness, so I went ahead and ordered it.
I was shocked at how good the soup was! It was on the salty side, but for a chain restaurant (Quiznos) it was amazing. I was even wondering if it was homemade, though I sincerely doubt it.
I got the impression that it was only for a limited time, and I don't know if it was a regional option or not. I had it at the Quiznos in Williston, VT near the Majestic 10 cinema.
