I came in with absolutely no idea on how to make what i wanted happen happen but Marty made it happen. Marty helped me so sweetly, i gotta love a lady who i can go and back forth with and not have to watch my mouth. If i lived in SF i'd come here for every party i threw. read more

Such a beautiful local spot with EVERYTHING you need, including amazing balloons that lasted days!!!! A long-standing gem in Noe Valley. The owner's name escapes me now because I'm late in this review, but she is LOVELY and so helpful. Such wonderful vibes at One Stop Party Shop!!!!! Please support this business!! read more

It's always great to have a range of local businesses, but let me tell you, the owner of this shop is a real piece of work. I've been there a few times, and every encounter with the owner has left a bad taste in my mouth. Consistently rude, always trying to sneak in items I didn't order, like different colored balloons instead of those I asked for (because she didn't have enough and thought I wouldn't notice). Today was the last straw. I came with my stroller, and you would've thought I committed a crime. I get it, moms with strollers can be a hassle, but come on, the shop is in Noe Valley, aka Stroller Valley, so expect some moms with their little ones. As I entered, the lady at the register muttered, "It's kind of tight inside." I got the hint and wanted to find a corner to park the stroller while looking around. The owner was buzzing inside and, at some point tried to squeeze past me - no space. She went around as I tried to rotate and leave the shop. She bumped into me again on my way out and said "Geeeeezzzzzzz" right in my face Save yourself the trouble and go to Party City in Daly City. The owner should be more transparent instead of passive-aggressive. Just put a sign outside of your shop that people with strollers, crutches, the disabled maybe even older crowd are not allowed inside because we block aisles, walk slowly, etc., and learn a thing or two from the folks at Church Produce on 30th Street. They know how to treat their customers right. read more

Really rude customer service. Kept saying that there is a shortage of helium because she doesn't want to fill balloons even though it is included in the price. Nothing fun or nice about this place. Avoid! read more

Marty is the Real Party @ One Stop Party Shop. I bring my Kids there all the time just to see Marty the Girls Love her and her Party Shop. She has the best Costumes and party supply's in S.F.C.A. We saw her today and she was packed for Halloween so we grabbed a few items and went on our Marry way. Thanks Penelope, Stella, Brittney and I. Penelope Loves her Balloon! read more

One Stop Party Shop - Balloon and Penelope Happy Halloween! - Party Supplies Near Me - San Francisco, California

Horribly rude and unwelcoming owner who clearly did not want me in her store. I've lived in this neighborhood all my life, so I gave this place a second chance based on urgency and convenience. The second visit gave even more venomous vibes than the first. I would rather go miles out of my way than set foot in here. read more

Marty, the owner, couldn't be more helpful and this shop is absolutely wonderful, particularly to find anything and everything fabulous needed to help celebrate with color and pizazz, each and every day of these prolonged days of isolation and quarantine! We are so blessed to have this fabulous shop right in the heart of Noe Valley! read more

Amazing selection of costumes, for both kids, raunchy adults, normal adults, burning man, and of course Halloween. Really good prices for being in SF too!!! The owner was great, helped me find a wig in no time for my Pam Anderson costume, and she was hilarious. Wig was only $45. read more

Staff is so kind!! And fast service. Amazing place to get birthday balloons. Call ahead and they will be ready for you read more

One Stop Party Shop - Balloons!!! - Party Supplies Near Me - San Francisco, California

I love walking past the One Stop Party Shop, the window display changes with the season and this month it's SPOOOOKY! They have wigs and costumes year round, but this month it's Halloween Central. Spooky masks, sexy costumes, glittery angel wings and red little devil horns, they have quite the selection for your costume inspiration. I plan on putting mine together earlier this year and save myself the scrambling around trying to put something together. I remember when this store first opened, my sister and I were one of their very first customers. We lived nearby and eagerly anticipated the opening. We could not wait to spend our money here and would just as soon as we got it. My mom gave me a $2.00 bill and instead of saving it, I spent it on some kind of fun new toy, novelty item or candy. They put it up on the wall and it stayed there for years. I still feel like a kid when I shop here. It's a fun little local business that provides fun year round. read more

See all

Just from looks alone, you couldn't convince me this party shop was indeed a one stop for all things costume related. Who knew that in one of the most residential spots in the Noe Valley was this tiny corner shop, stuffed full of party essentials? I'm pretty certain I'm not the only one fooled by this. But alas, One Stop is indeed what they say they are. A one stop shop of various party materials, from balloons to costumes to party favors. Depending on the time of the season, the store gets decked out in accordance to the theme. So if it's Halloween it's pumpkins, gouls, and witches. Mardi Gras is all things Bourbon Street and the masks / beads to boot. And so on. I'm always here for costumes. Whenever work parties or Halloween parties are on the horizon, I've learned it's probably a safer bet to explore here than it is bouncing around to various temporary party spots throughout the city. The prices are a little spendy, but that's how party shops make their money. And of course, always call ahead for a specific item. I certainly did and that's why I keep on coming back. read more

I don't know why I haven't made it into this shop before... perhaps the bad reviews scared me off for a long time, but this is now my go-to party shop! They have *everything*! Balloons, all kinds of themed decorations, cards, costumes, and party accessories like beads, masks, hats, headbands, noise-makers. I was most impressed by their amazing selection of Mardi Gras masks - from gorgeous, hand-made Venetian masks to cheap plastic and everything in between, including some locally made masks. The shop owner was very friendly, helpful and informative about their inventory and says that they keep this amazing variety year round! Wowza - I'm officially a fan! read more

One Stop Party Shop - Huge selection of Mardi Gras masks! - Party Supplies Near Me - San Francisco, California

Boy george, i'll tell you.. this is a store for masks. Fun mask, mysterious mask, movie mask, and my favorite: frightening clown mask. I found a bone-chilling latex mask resembling an evil clown for a very reasonable price at this store. I wore it to pick up my son from school! Boy were he and his 3rd grade friends shaken when they saw that haunting mug peering at them through their math class window! They all cried and cried! Hahaha! I'm in trouble with some parents and now I have to volunteer at the bake sale.. But it was all worth it, and now I can frighten my son almost every night! read more

This shop is adorbs and if you're creative enough, you can put together a costume of your own or buy one already made on the shelves. The lady was super nice. I went with someone who bought a top hat and some other things. All I needed for my costume was balloon ribbon, so the lady behind the counter just gave it to me. LOVED her kindness. :) read more

I called ahead to order balloons for my son's birthday party. (Note: preordering is required during the whole month of October due to Halloween). I asked to pick them up at 9:30 and was told that they don't open until 10:00 so the earliest I could pick them up was 10:15. Since the party didn't start until 11:00 I agreed to the 10:15 pickup and gave my credit card number over the phone. On the day of the party, I showed up at 10:15 and the store was closed. I knocked a few times and the owner showed up (maybe she lives upstairs?) and was really rude ("can't you read the sign? We're closed! Come back after 11:00!). It's too bad since there are not many places to get balloons in the city. read more

My roommate and I have both gone here on separate occasions and found whoever is working to be rude and cold, no matter who it is. Unfortunate since it's a cute shop! read more

Great neighborhood store. Small but ask for help if you don't see what you want right away.

Slutty nurse? NO. Hoochie ladybug? NO. Clichéd cheerleader? NO. Beer wench? NO. Flight attendant? NO. Bacon & Egg Couples Costume for $50? L-O-V-E. http://site.fantasytoyland.net/yswimages/fm-ras-7096.jpg read more

I have been here twice and found the service to be terrible. Don't bother coming here with a baby, strollers aren't allowed. I guess if you're handicapped, you're also not welcome. read more

One Stop is truly unique, with a wide array of party items and an owner, Marty, who provides service far above the average. My wife and I arrived shortly after closing time while the shop was being tidied up for the next day. Marty let us in and asked about our needs, which was to gather hats to support a friend who working through a severe illness. She listened patiently to our friend's plight, and spent extra time selecting colors and styles that might bring a smile to a planned gathering of family. Other places we've been have a similar array, but none have the quality of owner! read more

We had a bit of a mishap with our balloon order. Two of the four balloon colors had been discontinued. So when I went in to pick up our balloons, I was unhappily surprised. The proprietor tried everything to make me happy. How about a big balloon fish? What if we just doubled up on the available colors? Maybe we could fill in the missing colors with standard balloons (instead of Mylar, which is what we ordered). None of her suggestions were satisfying me. Finally, she gave us everything: more Mylar balloons in the available colors and standard balloons in the missing colors and... she gave us our money back. She basically said that she would rather have a happy customer than try to make an extra buck. When I got home with the balloons, my wife was blown away. We knew we had to write this review. It's the least we can do for such exceptional customer service. Give this woman your business. You won't be disappointed and she deserves it. read more

There is nothing but truth in the name One Stop Party Shop. They literally carry anything and everything that you could think of for Halloween. They offer a variety of wigs, capes, scary masks, Venetian masks, and costumes. I recently stopped in to grab a red superhero cape to complete my Halloween costume. I called in earlier in the day to see if they had any. Not only did they have plenty of capes but they also put it on hold for me until closing. During Halloween, they are open until 10 p.m. which was perfect for me so I could stop in after work. The costumes, capes, and accessories are all of good quality and it ran me about $15. Not too bad! Thankfully they are seasonal so you can find something fun no matter what holiday or special event you are celebrating! read more

The owner has really bad attitude and rude to us, feeling offended. And the shop was not a good one.

I am really surprised with the sour reviews for One Stop Party Shop. I needed some themed decorations for my Superbowl party and came across OSPS online. They had football plates, napkins, confetti, a centerpiece, football streamers, football food picks, stickers, balloons, football plastic serving dishes, tablecloths all to choose from for my party. The owner said it was what she had left so I can't imagine what I missed the day before. They have decorations for everything! The space is small and there is a lot going on in every corner but the owner offers a huge selection for whatever designated current event and/or holiday that's coming up. I had a great experience with the gal behind the counter. Based on the other reviews, I could see how catching her on a bad day might cause the animosity, but small business owners have a lot to deal with so give her some slack. She was super helpful and showed me around to all my requested items. I will definitely be back again and again in the future for my themed parties. read more

Great spot for wigs and masks for a masquerade or costume party. Came here after passing by on a run and had a costume party that weekend. The shop has a lot of wigs and costumes for children. Honestly I'd love to bring my niece here and get her some fairy wings or a princess costume. Anyway, next time I feel like stocking up my box of costumes (something ever San Franciscan should have in their bed rooms) I'll stop by here. read more

Sorry for the delay in writing this review. This was my first visit to this store. On Sunday mornings as I go to church, I always look at this place and admire the windows,etc. Well the day before St Patty's Day, I was in the neighborhood and was very excited to see that they were open. I went in and the owner, Mardie, was absolutely wonderful. She greeted me very warmly and was so helpful. She helped me pick out beautiful balloons for my St Patrick's Day dinner. She made my day and my holiday complete. She is so incredible and their selection of product is great. I will be going up there very very soon again, because Easter is right around the corner!! Check this place out, you will be amazed read more

This place has the best selection of Venetian and masquerade masks that I have found in the city so far, hands down. They get shipments several times a year of hand painted masks from Venice, which are great if you want something unique and collectible. They are usually around $60 a piece. They have even more replicas, which have fantastic designs and are extremely reasonably priced for how great they look. Tons of options around the $15-$20 price point. Every time I go looking for a new mask here it is difficult to chose and tempting to get more than one. Makes you wish there were more occasions in the city to wear masks during the year. read more

Support Local Businesses! This little shop is such a delight. I went in, asked for a captain/sailor hat, and 2 minutes and $8.75 later, I walked out with one in my hand! The shopkeeper was friendly and helpful. Her little dog is a cute greeter as well! read more

I LOVE this little store! The woman who runs it is ADORABLE & so is her little doggie. I used to live down the street and loved coming here for party supplies, balloons, masks, all kinds of costumes, plates & cups in all kinds of colors, and she even carries Burning Man gear when that special time of year rolls around. If she doesn't have it, if the woman can, she'll special order anything for you in her catalog! I moved across town and I still come straight her for any party supply needs because I know she'll have exactly what I want. read more

My boyfriend and I were in need of Venetian masks for a black tie gala at the De Young in February. I ended up going to this place because it was one of the few SF stores that popped up on Yelp for a search for "venetian masks"! Definitely glad I came here. The owner was very nice and helpful while showing us all our options, from the pricier real Venetian masks ($50-$100) to the more affordable fabric ones (around $12-$18). I ended up with a $14 fabric mask and my boyfriend picked out a $50 Venetian one. Now I can't wait to go to the gala! read more

6:15 pm... 1/4 hour after closing, they re-opened for my friend's emergency. 15 minutes later, she had spent twice the time they had stayed open late..... $60 for some balloons is retarded. Not sure if that is my ladyfriend's fault? I am thinking this place is a neighborhood place (good), with a whole mess of worthless crap that costs too much sold to you by someone who didn't really seem to care at all. Would be less stars, but they opened for Lauren and that is alright in my book!!!!! read more

This little shop carries every fantasy I could think of. Excellent choices for adults and kids, from sweet costume choices to gruesome and beyond scary! The shop owner is very generous and thoughtful, as well as incredibly organized and clearly knows what it takes to run a small business. With her in charge, this is why this amazing shop has been successfully up and running year to year, for the past 30+ years! read more

Been around this place for a min of 25 years. They always have what I need or can get it quick. Support LOCAL business.

This store was amazing and had the BEST selection I've ever seen for Halloween costumes the weekend of Halloween! They made my boyfriend's priest fantasies come true with a cross and all! Great wig selections, costumes for all ages and genders, with the best accessories. Party City, who? read more

Great place for all your Halloween needs. Tones of Costumes. Lots of stuff you don't see at a box store.

Terrible customer service!!! Both my wife and I called them to ask questions about children's halloween costumes. The salesperson on the phone sounded exasperated that we were even bothering her. Her words were "I don't have time to talk to you, I am too busy". Such arrogance does not deserve your hard-earned money! read more

Do not bother. I live a block away and tried on three seperate occasions to enjoy this place--forget it. The store owner is rude and cannot be bothered. Today when I stopped in she was ranting and raving to a friend (the last time I was there she was ranting and raving on the phone)...about someone who ironically "has no class." The store is so tiny its impossible to not be subjected to her pissy attitude. read more

The name completely sold me! A one stop shop in my neighborhood? Sold! I'm so there and ready to buy out the store. Unfortunately, as I walked into the store, I tripped over a dog carrying case which was foreshadowing. I made my way through the store (aisles were tight), but found the party plates and napkins. They have all the basic colors: blue, pink, red, but that's about it (plain). They also carried a couple of themed items: Chinese NY party favors and some items for Mardi Gras, but beyond that there wasn't anything that really screamed party to me. It was difficult having to make my way through the aisles and watching every step and trying to look for party plates. It's good to know that this is a few blocks from my house for convenience, but if you are looking for more specific items, this may not be the place. read more

I wandered into One Stop Party Shop on New Year's Eve and found a great selection of every imaginable party favor. What I found extraordinary was that the owner, seemed to want to make me happy even if she was undercutting her own price margins! Instead of taking advantage of a customer who was desperate for new years eve items, she seemed more interested in making sure I was getting the best deals imaginable. I bought fancy New Year's Eve top hats and a feathered tiara and balloons and when I walked out of the store I felt like they owners were just excited to be sharing their largess with a happy customer! How many times do we shoppers go into 'party stores' and feel like we are being ripped off? Not at the One Stop Party Shop, where I felt like a guy who had won the lottery, by simply having the good fortune of walking into this extraordinary store. They had great costumes and all kinds of party items from birthday parties to just great paper plates and other party favors. If you live in the neighborhood , One Stop Party Shop should be your must go to store for all your party needs, whether it's for Halloween or just a party for friends and family. I was visiting my daughter who lives on 28th Street, and she was having a New Year's party that night and was ecstatic with the items I brought to her apartment. If I lived closer, I'd be shopping there all the time, but unfortunately I live just outside of NYC, a mere 3,000 miles away! read more

Party shop with an attitude...a bad one. I may be wrong, but everyone involved in the party shopping experience should be happy. It should be like buying ice cream...smiles all around. Not at the One Stop Party Shop! This is serious bothersome business for the person behind the counter. I received better customer service from the shop owner/worker's tiny dog. I really don't want to bother you with the gory details, so if you're in the partying mood and want to stay that way....try another shop (or send your grumpy friend). read more
