From the reviews

We had our wedding reception a few days ago on 11/03/24. From start to finish, our wedding was nothing short of magical, and we have to give a huge thank you to Brandon and the staff at Diamond Seafood Palace 3 who made it possible! We worked with Brandon for our big day, and we can't recommend him enough.

I recently held my wedding at Diamond Seafood Palace earlier this month, and I can’t say enough good things about their accommodations, service, and attention to detail. Their team and staff went above and beyond, exceeding not just my expectations, but those of my family and guests as well.

Getting married at Diamond Seafood Palace 3 | Wedding Venue

A castle wedding is the once-in-a-lifetime, storybook kind — the grand staircase, the ballroom, the gardens and turrets your photos will live on forever. Castle weddings commonly run $10,000–$40,000+ depending on the date, guest count, and how much is included, so ask for a written quote for your season — Diamond Seafood Palace 3 | Wedding Venue doesn’t publish a set price, and tiers move fast. Two things make the tour worth the drive. First, see it at the time of day you’d actually get married — a ballroom that glows at golden hour can feel very different at noon, and you’ll want to walk the path your guests take from the gates to the ceremony to the reception. Second, bring your real questions: what’s included with the venue fee (tables, chairs, setup, teardown), the catering and bar policy, whether you can stay overnight on-site, the rain plan for a garden ceremony, and the music curfew. Fairytale dates at castle venues book 12–18 months out, so if the tour feels right, ask what’s open in your season before you leave.
