"Whether with a large group, like a wedding, or a small group, like the memorial gathering today, The Gateway Center is always professional and so kind. I had so much to do to prepare, but the actual event was effortless thanks to them. Their venue and catering staff is well worth the money. I’ve used them before and I will definitely use them again." - Greg Amsler
"Beautiful space. The meal was served to hundreds of people within minutes. Smoothly done. Very tasty too. I am vegetarian and had not asked in advance to have something prepared, but when I told the server a vegetarian plate came right away. The staff were efficient and friendly." - Robyne O'Mara
