Zilli was the best vendor we had across everyone we worked with for our wedding. We wanted our theme to be quintessentially Wisconsin, with a traditional fish fry, etc. and they delivered. From the initial tasting (which was outstanding) through to the day-of, they grasped our theme, asked the right questions, and did a great job of having answers for those things we hadn't thought of (two-sided buffet so people are served more quickly - awesome.)
The food was great and we got nothing but compliments from our guests. They also accommodated our Wisconsin custard for dessert, which we brought in from outside, but they were still willing to dish up on demand. Zilli is not the cheapest around, but not the most expensive either -- not even close. With a limited budget, we decided that rather than get B-list vendors across the board, we would pick a few that mattered more to us (food, DJ...) and spend more, while saving in other areas.
So glad we chose Zilli and would recommend them to anyone with very specific needs looking for flexibility. Lastly, our coordinator Heather had a baby during the months before our wedding and no one at Zilli missed a beat with our event!
