Party planning can feel like a burden… but it doesn’t have to

Entertaining is an art – when done well, the right party creates meaningful memories for everyone involved. But it’s hard to be a confident host when you’re too busy worrying about how the party will turn out.

At Diddams, we understand how challenging it is to bring all the pieces of a party together. But we also know how impactful it can be when those pieces come together just right. That’s why we’ve spent more than three decades helping customers like you create celebrations that make people say, “WOW!”

Here’s how we do it:

  1. We listen to your ideas to understand your vision
  2. We contribute some of our own ideas to help bring it to life
  3. Together, we’ll create an event people will never forget!

For us, it’s all about relationships

Our culture is based on active listening, making people feel special and relationships that last. Most of my employees have been with me for many years — which means when you come into our store, you’ll recognize faces, build friendships, and feel taken care of.

Our superpower is making your party a success. We go above and beyond with free guidance on all the details — plus, you’ll get access to our knowledge based of the best venues, caterers, table rentals, bouncy-house services, and more.

When it comes to Balloon Decor Design, there’s no vision we can’t bring to life. We mean it when we say, “You dream it, we’ll do it!”.

  • We’ll bring your vision to life, regardless of your budget
  • You’ll be WOWed by our custom balloon decor
  • We’ll be on time and on budget
  • Our balloons will sometimes pop (and we’ll cheerfully replace them)

Show your loved ones how much you care with a meaningful celebration.

Too many people end up stressing out about their party, simply because they didn’t have a partner who could help them plan AND execute all the moving parts. You love your people too much to let your celebration be lackluster. Together, we’ll create an event that will make them feel special – while also helping you feel confident and relaxed throughout the process.

It’s been years since I’ve been in the store just because I don’t live in Mountain View anymore. But before I moved they had already taken over the store that was next to it and expanded their Halloween section. So coming here I already knew how big it was but the full size of it just kind of shocked me again lol.

We were greeted as soon as we walked in, they have a huge selection of balloons to the left and they will even blow them up for you. As soon as you walk in and you look slightly to the left I think that’s where they have like the seasonal items because they had a huge Valentine’s Day display there, behind it they have a huge and I mean absolutely humongous candy selection which is amazing because they have a lot of like nostalgic candy that I haven’t seen in years.

They tend to organize the store based off of whatever event you’re looking for so pretty much anything you need is going to be in one spot. We needed some retro items for our daughter for spirit week this week so since we were going to be in Mountain View we decided to come here and we found a cute poodle skirt and pink glasses, and white poodle socks.

I’m not sure who had more fun in here, me or my kids to be honest. They apparently also sell bath bombs here! This kind of shocked me but it was really cute because they were shaped like donuts and they had like rainbow sprinkles on top. I also needed to make some Valentine’s Day treat bags so I was able to find some pencils and little pads of paper and erasers here which was perfect!

I really enjoyed coming here because they had exactly, and I mean exactly what I was looking for, and I don’t feel like I spent too much based on what I was getting. And also it was kind of hard to find retro clothing for my kid anywhere else so just the fact that they even had it in stock and right there for me to just take home, I would’ve paid anything for it haha

Overall this location has ample parking, a huge Halloween section, plenty of party decorations, friendly staff and fun nostalgic candy to bring the kid out of you. I would absolutely recommend coming here for party stuff, event planning, Halloween, even fun dress-up days for your kids school!

10/30/21 went to buy JJ’s Harry Potter costume and was surprised that they offered to try the outfit before we bought it. The salespeople were very friendly, checkout was easy as well as parking. We often check this store out before we go to other stores and I am happy we found the gown for JJ.

This is the best party store in the bay!!! I love the wigs balloons costumes and more! One stop shop for all your party needs! Great people full of love and diversity and great products full of fun! 🙂

Love coming here, especially for the balloon selection and the sticker wall. The sticker wall is so unique, I hope they continue to restock it because last time I went, the wall was almost bare. This place beats most other party stores by far!

This store had hands down the best selection of party supplies! They had many many aisles of tableware as well as coordinating decor. Whether you need child birthday supplies or wedding supplies, this is the place!

This location will be the closest to South Bay by 2020 as the Almaden location has lost their lease.
