What is it about ZeroCater that provides better services than competing caterers in the area?
b) the food is great
c) it's super flexible - if you don't like something, just tell them
d) the variety
e) you don't have to decide what you want (some people would say this is the best reason)
f) it's easy as hell
That said, ZeroCater still has its own problems. The biggest one we've had is ZeroCater simply not listening to our requests. It took us a while to get a gluten-free option, for instance, and even longer to get it removed when we no longer needed it. We've also requested no fish several times, and yet we still end up getting fish on occasion.
Overall, though, I'd recommend ZeroCater if you're planning regular team lunches in a city where they offer it and you don't want to deal with the minutiae of it.
