I had the Option, which has, in place of a regular burger patty, a breaded and fried portobello mushroom filled with a lot of cheese. It reminds me of the Shake Shack veggie burger.
I also had the chili cheese fries, except they were out of chili so they made some onion-french-fry concotion instead. Both were pretty good but I'm not sure I'd come back since it's slightly pricey for what you get, the restaurant is very tiny, and the food is not particularly special to me.
