Disclosure: I received this product at reduced cost in order to give my honest opinion and let you know how it worked for me.
So we definitely like to throw parties at our house, especially since I finally own my own home. That being finding a good way to keep things cool while displayed has always been a challenge until now. The Inflatable salad bar from Kovot really does the trick. It's super easy to inflate as it's only the ring that inflates and the bottom stays flat so that it stays level on the table top. If you can't tell from the pic above we mainly used it for drinks, but I could definitely see how much space could be utilized for potato salads and other items that would be best served cold.
The only thing that we didn't like was draining it, with the little drain on the bottom it was far easier to take it outside and for our next shin dig we will put it on the outside table so I can drain it easily.
Looking for something for your next party head over to Amazon and pick one up!
