The only thing NIbblers is good at is being on time. (Kind of...)
I ordered basic box lunches, tea, coffee and water for an event for 80 people. The bill was $1500. That comes to $18.75 per person. The sandwiches were those things that have a lump of stuff in the middle which are then cut in half to display said middle. What you end up with is mostly bread.
The tea was in gallon sized plastic milk jugs which were just left on the table. Just like everything else, there was no presentation at all. They were on time, but forgot to bring several things so they had to run back to Hq and get them.
I don't have a lot of experience with catering, so maybe for 20 bucks a person you shouldn't expect much, but this was just cheap, cheap, cheap. I would not use them again.
