One shouldn't expect a largely vegetarian restaurant to present a shining example of a cheeseburger, and Tree huggers is not a surprise on that level. My burger was just shy of well done instead of medium, and it wasn't the tastiest, but it was pretty okay.
On the other hand, the sweet potato fries and my banana-espresso smoothie were pretty great, and everyone who joined me seemed to love their food.
The menu and the server emphasized that they would cater to any allergies or needs, and our friends proved it true!
