My wife and I just had our wedding at the New York Botanical Gardens in the Bronx three weeks ago. The wedding was gorgeous (we got compliments on everything from ceremony through ...last song), and we are still coming down from the excitement!
*Pros*
The NYBG itself is a magical place. The grounds are stunning in every season, the plants are immaculately maintained, and the architecture is beautiful yet unpretentious, so that it enhances your event rather than distracting from it. Along with the Garden comes Constellation Culinary Group, who provided top-notch food that left our guests completely stuffed and yet still wanting another round of everything. Honestly, picking our menu from among Constellation's options was one of the hardest things we had to do. Everything from the more basic sliders, fries and mac-n-cheese to the more unusual pastrami-roasted carrot salad, smoked salmon rillette, and horchata shooters was outstanding (we even got compliments from some of our picky eaters!). The day-of staff were on point, taking care of things like fetching an extra dress-steamer, setting up the decorations we brought, directing wandering relatives, even holding aside a plate of cocktail hour food for my wife and me, since we had to miss it to take photos (thanks, Sasha!).
*Cons*
There were a few fairly major construction projects at the Garden that started some time after we had put down our deposit, and continued through our wedding date: the main dome of the Haupt Conservatory was being renovated, the Great Lawn was fenced off as exhibits were being changed, and the pergola in the ceremony space simply got removed due to its getting old. We had expected some seasonality when choosing a botanical garden, but these changes were fairly dramatic, and while they didn't directly impact the ceremony or reception spaces, the various construction tarps and fences were a bit of an eyesore in our photos. To their credit, Constellation was pretty flexible (offering us alternative photo locations, extra setup time, etc.), but we would have appreciated more of a heads up that these changes were coming in the first place, since some of them (like the pergola removal and an extra layer of construction tarp on the conservatory dome) we didn't learn about until we went to the garden for our second to last or last walk-throughs.
