Diamond Bar Center

Great parking. Amazing views. Very nice staff. This facility is amazing with spectacular views.

My friends wanted to go for a hike here. I've never been and wanted to join. It's a holiday weekend so it wasn't crowded. The view of the city was nice but there's a lot of weeds and wildflowers along some of the trails so if you're allergic, make sure to be extra careful and wear pants instead of shorts. Some of the trails have steep parts but there's so many routes to choose from. We went for about 1.5 hour and had a good time.

Professional, Friendly, Helpful, Prompt, Respectful, Great Space for any event!Mei, Niko, and Christian provided us with excellent service last week. They were fast to assist and answer any questions as well as work with us on short notice for a memorial luncheon following funeral services for our Father-in-Law. Their efforts and professionalism really helped relieve a ton of stress for the whole family.YOU GUYS ARE WONDERFUL!!!HIGHLY RECOMMEND this venue!!!Thank you again, so very much!!!Cheryl Dietz, Lori Keller & the Keller Family

The Diamond Bar Center features as a large venue for meeting and activities. The banquet facilities can host parties for few hundreds of people and up to one thousand max capacity for meetings. There are large parking lots conveniently around the establishment.

I had my wedding here this past September and I'm so glad I did. Everyone on staff was so helpful and kind and the views were beautiful. For a place like this with such a reasonable price to book I was very surprised. Thank you diamond bar center for making my wedding day a dream come true!

Getting there:Once you enter the driveway there is parking to the right which is essentially right in front of the venue. If that lot is full you can park in the additional parking lot that is to the left when you enter the driveway.Experience:This venue is not only beautiful and spacious inside, but the views are immaculate. You don't realize how high up you are until you're at the top. The staff is super friendly and were on top of the clean up situations for our event.

This is a nice large venue. The venue has a big parking lot and plenty of Handicap spaces as well to park in. There is a beautiful outside patio and a large room which is perfect for large events. It's located at the top of the hill overlooking the city of Diamond Bar which is a beautiful sight at night.

I came here to attend a wedding and this one thing that happened really bothered me. They party was asking for their wedding cake and this location insisted they only received a certain size of the cake. This was stressing the bride and groom out because from their understanding the cake was delivered. The bride called the bakery and asked them what was going on and she was in the corner clearly upset. The vendor insisted they dropped it off at this location. It turns out this location misplaced it and they found it. I would never want to stress on my wedding day. This could have been clearly avoided if the location was organized or if they did a thorough check. One of the workers asked "are you sure they brought it.. it might be in another room.. I just need the key to that room" this was before the ceremony... after the ceremony when the bride and groom are now married they still couldn't find the cake then again insisted it wasn't there. Like I said they eventually found it but I feel like it was lack of trying, because clearly it was there. Again this is a guest pov and as a bride I would never want to experience this on my wedding day.

Nice location with beautiful view from balcony. Building is fairly new. Was attending a banquet but this would be perfect to hold wedding reception.

I scheduled my event for September 2025 in June 2024. In January 2025, I received a notification from the center informing me that my event had been canceled due to a city project. This situation has caused significant frustration and inconvenience. I have already arranged for a mass and vendors for that date, for which I have made payments and provided deposits. Consequently, I was compelled to search for an alternative venue. Additionally, it is particularly aggravating that the return of my deposit for the venue may take four to six weeks. It is unreasonable that they canceled my event; they should have been prepared to refund my deposit within a week of the cancellation. I am perplexed as to why the process of returning my deposit is taking so long!
