Pros: Very affordable ($6 lunch in Manhattan is impressive). Large selection. I am trying out restaurants I wouldn't normally try. A good mix of high and low end food. Very affordable!
Cons: The app wasn't super polished but it seems like they are slowly improving. The ability to quickly save favourite meals and re-select them is missing. The Brooklyn selection is very limited. Lots more people are using it now so meals get booked up fast!
