Everything ran so smoothly and we've received so much wonderful feedback from our guests, everyone loved the beautiful venue, the food and the wonderful service. The day was everything we could have hoped for and we're so glad that we chose Beta to host our wedding! If you could please pass our thanks onto the team that were working we'd really appreciate it.

Jojo and Brian and all the staff at the beta bar who worked the night of our wedding. Where do we begin! Thank you so incredibly much for making our love party as amazing as I believe it could possibly be!!! Everything seemed seamless on our end and our guests have absolutely praised all of your staff!! Everyone was so kind and friendly which is so hard to find these days and the service was absolutely on point! I don’t think there was a dry glass all night🥂 Jojo thank you for all of the background work you did to make our night as amazing as ever, Justin and I could not be more grateful! We cannot wait to see photos of your incredible venue, for now here is a sneak peak we received. Lots of love to everyone at the beta bar.

From the beginning the team at Alpha were beyond accommodating, helpful and a pleasure to work with. From the initial meeting at the venue to all the finer details with your self, wedding planning was made simple and such a breeze. There was not one ounce of stress or worry! The venue speaks for itself, it is timeless, elegant and just beautiful. It was so lovely to be able to have so many additions like the draping, lights and disco ball that just elevated the building. Please pass on our thanks and appreciation to Alpha dining, our dinner on the Friday night was absolutely divine - everyone left raving about how delicious the food was and how beautiful the restaurant is. The staff on the night were attentive, thoughtful and proactive in everything they did. The manager - my apologise I forgot his name, was consistently checking in and ensured that we had everything we needed! Nico our waiter was on-top of everything. It was the perfect pre wedding celebration and I am so glad we did this with Alpha. Everyone left wanting more and I have no doubt we will be back to dine in the future. As for the wedding, we have no words! It was incredible, seamless and everything we had dreamed of! Every person raved about the venue, service and especially the food - people are still talking about the food! I am devastated I didn’t get the chance to eat more!! Oscar and all staff were exceptional, they were sure to find Zac and I in the crowd to check if we needed anything, communicated with the people they needed to and ensured that the night ran smoothly. It was honestly perfect. Every guest I spoke to has said that it was the best wedding they attended so that is saying something! Thank you so much for all your support, guidance and professionalism throughout this process and the whole event, it was incredible and everything I had dreamed of. I have been recommending Alpha since we booked as I was already so impressed however I am now even more certain that Alpha is the perfect wedding and event location and will be sure to continue to recommend Alpha to anyone I speak to!
