I really wanted to love this place. I made reservations for our friends' wedding anniversary, hoping for a nice evening out. However, upon arrival, we were told we'd have to wait because a few other parties were also waiting for tables,despite having a reservation. The hostess suggested we sit at the bar but that's not exactly ideal for a celebratory dinner. I would completely understand if we were walk-ins or just there for drinks, but with a reservation, I expected to be seated promptly at a proper table. After waiting about 20 minutes, they combined two small tables for us next to the hostess stand where people were constantly walking by or waiting to be seated. I declined that spot because it felt too busy and lacked any sense of privacy. They eventually sat us elsewhere. As for the food, the Wagyu burger was excellent, I'd order it again if visiting. Unfortunately, our entrees arrived before our appetizer, the steak frites were bland, there was little to no seasoning, and both the steak and fries arrived cold. The chimichurri sauce was okay but also lacked depth of flavor. There was also a small issue with transparency on pricing. When my husband ordered the burger, he asked what options there were for fries substitutions since we were sharing the steak and burger. The server said Ceasar salad but never mentioned there would be a $7 upcharge. We only noticed the extra charge on the bill. It's not about the cost, but it would've been nice to have that disclosed upfront. Overall, the food was underwhelming and the service could use improvement. Given all the buzz surrounding this new spot, I was expecting a much better experience. Unfortunately, it was a bit disappointing. read more

Osa Rooftop - Burger, salmon crudo, ceasar salad - Bars Near Me - Pasadena, California

Checked out this new rooftop restaurant / bar in the AC Hotel in Pasadena. Today was their official opening day but was open a few weeks before for a soft opening. The decor and space is really nicely payed out for the small space. We made a reservation but were seated inside by the bar. We requested to get a better seat outside in the rooftop and was able to be accommodated by the manager. Both of our servers were lovely and made great suggestions. We tried the Fried Queso Fundido, OSA Burger and the Roasted Chicken. The Burger was perfection but the Chicken was all over the place. It included gravy, some kind of sweet sour sauce, tortillas and a celery salad with no dressing. Would not recommend, the kitchen staff faced some miscommunication but we didn't get out appetizer until after the meal. Brenda was amazing and took care of the Fried Queso Fundido, tried them at home and do not recommend them as well. The chorizo was more like a ground beef and the fried spheres are mostly filled with rice and none of the queso or poblano as stated on the menu. They did have a seasonal menu but did not get to explore. The atmosphere was nice a bit noisy as the tables are very closely to one another but the view and the breeze was great. read more

I'll start by saying that the food here is just not good and not worth your time. Maybe the drinks are better, but I wouldn't know. The view is just OK, nothing spectacular, and the service could be better. We started off with the Peach Burrata Salad, something we thought might be light and refreshing. What we got was undercooked broccolini with unripe peaches, covered with chimichurri sauce and some burrata. Could not finish, did not want to finish. We then received the salmon crudo, which tasted fine. Unfortunately there was only 3 pieces of avocado to our 4 pieces of salmon, I guess we just had to make do. When I checked pictures from other peoples crudos posted to yelp, they had 6+ pieces of salmon, so now we feel kind of ripped off. We also got the chicken tacos and burger, in which we might as well went to a local taco stand or in and out and gotten much tastier food for much less money. Maybe drinks are the way to go, but just skip the food unless you are starving. read more

Came here for my friend birthday.. walked in was pretty busy made reservation so go seated right away. First off view was nice overlooking the mountains. Looking at the menu there was not much selection. We ordered pork/ waygu with pesto which was just ok was missing flavor and ordered salmon/ avocado sashimi presentation was pretty it was pretty good but nothing special. We still hungry but decided to go somewhere else to have something better . Service was great and they very attentive. Overall I would not come back for the food but if you wanted to come for views and cocktails this would be place to go. read more

Osa Rooftop - The view - Bars Near Me - Pasadena, California

My husband and I tried Oso last night. The rooftop setting is charming at first glance, but the space is very tight--narrow, crowded, and a bit overwhelming. Unfortunately, the food didn't live up to the atmosphere. We started with the spiced nuts, which were served oddly in a martini glass. They were sticky, clumped together, and difficult to eat without a fork. The honey coating overpowered the light spice, leaving them more messy than enjoyable. The meatballs, a mix of pork and beef, were disappointing as well--dry, unevenly mixed, and not very flavorful. For our main, we ordered the steak and fries. The steak was cooked to medium, which was fine, and the fries were decent--hard to go wrong there. The cocktail I tried, an Aperol Spritz, was refreshing, but when we ordered wine from the menu, we were told it wasn't available and had to choose something else. Overall, I'd give the experience a 2 out of 10. The rooftop ambiance can't make up for the mediocre food and tight, crowded setting. Not a place I'd return to. read more

It's on the rooftop of the AC Hotel. Super cute entrance from downstairs. I was NOT expecting the food to be amazing. Wow. Everything we got was 10/10. My favorite was the peach burrata salad. The peach was so sweet and it melted in your mouth with the burrata. The dressing with the little crunches was amazing. The meatballs with the bisque sauce was also really good. The brussel sprouts were cooked to perfection with the perfect pomegranate touch and crunch. Chefs kiss. the ambiance was wonderful. Super chill. Our server Jordan was also really nice and attentive. I would def return. Cute little spot. read more

Osa Rooftop - Great rooftop beautiful views! Will definitely be back! - Bars Near Me - Pasadena, California

Osa Rooftop is such a hidden gem in Pasadena! The ambiance is gorgeous with unbeatable views of the San Gabriel Mountains. We started with their mocktails (so refreshing!) and shared a few small plates, highly recommend the tuna tartare, wagyu meatballs, and tostones. The burger honestly blew me away, one of the best I've had this year, and the steak frites under $30 is such a deal for a rooftop. Overall a nice addition to Pasadena! read more

Come for the view and drinks, skip everything else The rooftop view is stunning and the drinks are good - that's about where the positives end. Our server got pulled to bartend mid-service and basically vanished. Not ideal when you've got a babysitter on the clock. The peach broccolini burrata salad was a mess - weird presentation, hard to eat, and the burrata tasted off. My steak was aggressively salty (and I salt everything), and my fries came out like chips while my wife's were normal. Bottom line: Great spot for a drink with a view. Don't bother with the food. read more

Love the ambiance, vibes and service but wish they would have more food options. Not a fan of their food menu.

Parking: was able to find street parking Atmosphere: very well decorated and terrific views Service: great Food: it's good, but you'll be paying for the atmosphere Overall, very cool place to bring a date or anyone else you want to impress. read more

I want to start off by saying that the restaurant was super cute and the view was amazing! Two downfalls were that the steak was super dry and burnt. The fries were amazing but the steak was not. The second downfall was that the server that brought our appetizer was incredibly rude. When we asked if what she brought out was the queso fundido she responded with rude tone. Overall I would give this place a 7/10 read more

Osa Rooftop - Steak fritters - Bars Near Me - Pasadena, California

The setting at Osa Rooftop is hard to beat. The decor is sleek, the ambiance is lively without being over the top, and the service really stood out. The tuna appetizer was a strong start and had me thinking the rest of the menu would deliver. Unfortunately, the cheeseburger did the opposite. Something that simple should be a slam dunk, but it was so off I had to return it. Drinks were tasty but priced like you are in Hollywood, not Pasadena, which stung a bit. Bottom line: the views and vibe are the reason to come, but I will wait to see if the food menu levels up before making this a go-to spot. read more

The ambiance is truly picturesque, with a rooftop that offers a beautiful sunset view and a projector playing classic movies--a lovely touch that makes the setting feel unique. Our hosts, Javier and Emma, provided outstanding service. They were so accommodating, courteous, friendly, and attentive, which made us feel very welcome. While the bar experience before being seated wasn't quite on the same level--the service there felt a bit hurried--it may have just been a busy moment. Once seated, our server encouraged us to keep pace, which didn't leave as much room for us to linger and enjoy at our own rhythm. As for the food, I ordered the Osa burger and my boyfriend had the pollo asado tacos. The flavors were okay, though I personally would have preferred a bit more of that smoky, charred taste with the chicken. With a few refinements, the dishes could really match the charm of the overall setting. read more

Service is not there yet if they're going to have service. We were late five minutes and the hosts made us wait half an hour because we're late and there were tables ready and they sat people prior to us when their reservation was after us and the table they sat us was empty from the start. He just wanted to punish us. OVER RATED!! The view in my backyard is better Pasadena mountains but I'm local and love trying new places. Food was eh, lots of fried oily stuff. If service is bad and making reservations is inconvenient and service sucks, not sure if I care for this place. I will only go if invited, will not make an effort to go here again. read more

Had dinner on Saturday night, 4 of us, a double date. Thought we would check out a cool spot. That was about it, location was the best thing. Got an "Ol' California", their signature drink. About 2 Oz of colored water and a huge chunk of ice. Worthless for $18, wouldn't have paid $5.00 for it. Got the burger, got salad with it, that was an extra $7.00. So, an ok burger with 6 pieces of lettuce, $35.00. Was i told the salad substitute was a $7.00 bump? No. Not afraid of spending $ for a good dinner, but got hit with a $500+ tab that should only have been worth maybe $150.00. Don't waste your time or $ at this place unless you dont like your time or your $. read more

Beautiful Views, Disappointing Service (Unless You Sit at the Bar) This was our second visit to Osa Rooftop, and unfortunately, it was rinse and repeat. The service in the dining area completely misses the mark. It's a gorgeous location with stunning Pasadena views, but it feels like the staff assumes guests come here just to sit and look at the hills instead of actually enjoy dinner and drinks. The front desk gets ! Warm smiles and a friendly greeting every time. We were seated quickly, but then it took forever just to get water. We sat watching servers wander around while our glasses stayed empty. There were only four tables occupied, so it wasn't busy. When water finally came, it was warm with no ice. I'm guessing the bottom of the pitcher. Knowing how slow service was on our first visit, I immediately ordered my cocktail. Still, it took 45 minutes to arrive. When I mentioned the wait, the server said, "It's only been 10 minutes." It was 4:38, and we'd arrived at 4:00 for a 4:30 reservation. I also ordered Brussels sprouts right away (lesson learned from visit one), and those took 30 minutes and of course cold when they arrived. Obviously they sat in the kitchen under a warming lamp that didn't work. When I asked again about the drinks, I was told "the bar's backed up." There were four people behind the bar looking busy with side tasks, but no one actually mixing drinks except two that actually were possibly the bartenders. At that point, I'd had enough. I took my cold sprouts and moved to the bar. And honestly? Everything changed. The bartender was amazing. Water came immediately, my cocktail was perfect, and when I ordered another, it showed up almost instantly. The difference between the dining area and the bar is night and day. There's a serious disconnect between the kitchen, bar, and table service. If management could fix that, this place could be incredible. The location is beautiful and the vibe is great, but the slow, disjointed service keeps it from being the experience it could be. People would absolutely order more food and drinks if things just moved faster. If you're coming for the views and a relaxed drink, sit at the bar and not the high tops. That's the only part of Osa that truly gets it right. read more

Ordered their burger and steak/ frites. The ambiance was nice and modern. The burger was okay, nothing to rave about or pay $26 for. Although the steak was so underwhelming, asking for medium rare and getting medium well instead. Got presented with basically leather, it took my partner and I a minute to chew each piece. Left my jaw feeling so sore after when I sent back the steak, the remade steak felt even chewier than the last. Their cuts of meat are cheap for the price you're paying, rather go to sprouts and cook it myself. The only thing good about this experience was the red haired girl who was nice and understanding the whole time.(wish i got her name great service to u!) If you don't finish your food don't worry the overwhelming amount of gnats will finish it for you. read more

Pros: The view and some of the bar area staff (KC, Eliot, Xavier, and Oscar to be specific) were great! That's it. Cons: Checking in a disjointed. We couldn't make a reservation because their system wouldnt allow and when told the hostess, she said it was because they were booked. The food was subpar...and we also received it way after folks who ordered after us. Also, we could see the chef (which we later learned) carrying in produce that was sitting in stacked boxes visible to the customer. Overall thoughts is training is needed, system needs updating, and maybe shifting things around at the bar. read more

Worth visiting around Sunset for the view. In short food is fine, drinks are fine, service is good. It ends up being a better than average hotel restaurant rather than a real destination restaurant. Arrival was a little odd. I later found a crazy tunnel with billowing fabric and strange lighting that I suppose is the intended entrance, but initially entered through the lobby, and guessed that I just go up the normal guest elevator to the top floor. View was immediately stunning. Decor is good if de rigueur. Feels like a budget version of the decor at Agua Viva at the Conrad. Menus are initially impressive but ultimately annoying. Heavy leather bound with a strap, paper falling apart inside. Odd to mention at all, but they kind of demand attention which is annoying in itself. We ordered "Marinated Stuffed Olives" which were actually olives fresh out of the jar stuffed with Queso??? One of the worst dishes I've ever been served at a restaurant. Looked disgusting, tasted awful. Also was just a shock to the system. Felt like a prank. Otherwise we had Tacos which were better than average, and steak frites which were about what you'd expect for a hotel steak frites. Really tasty fries and average steak. The cocktail menu was done by the mixologist from Capri Club, which is why we were excited to try this restaurant, but it ultimately is pretty standard hotel cocktail fare. Understandable to play to the middle for a hotel restaurant, but disappointing. A fine place to go if you are staying at the hotel or want somewhere to watch the view, otherwise skip it. read more

Food was great and the ambiance is amazing, the space is beautifully decorated and feels intimate. But we went through 3 different waiters throughout dinner and they were out of most of their wines on the list which was frustrating. Will give it another try since the food was so good. Get the brussel sprouts! read more

Perfect spot for a dinner date - cozy atmosphere, great service, and amazing food. You won't be disappointed!

The food is a little pricey for what you get, but the ambiance makes up for it. Osa rooftop was a great experience! We ordered shoe string fries for appetizers, swordfish and chicken tacos for entrees and had the chocolate mousse cake. All were amazing! We went at sunset and saw amazing views of city hall and other buildings. The ambiance was amazing and they started playing Casablanca on the side of the building. I was perfectly. We will definitely be back soon! The service was a bit slow, but the staff were all friendly and helpful read more

Osa is a really beautiful rooftop bar and just what Pasadena needs. We were really excited to celebrate our friend's birthday here. I know they haven't been open for long, but service was still disappointing. The servers didn't know their alcohol list, or the food menu well. They were out of a few food items that we tried to order because the night before was busy. My husband tried to ordered three different drinks which they were also out of. One was a beer, a liquor based drink and then an iced tea. Our server didn't even offer to make iced tea, she just laughed and said they were out which I found rude and unprofessional. The steak frites were really yummy, but the servers forgot to put in two of our tables appetizers. They finally came out over an hour later after having to remind them multiple times that we never received them. I understand that this is a bar, but it is also a hotel, so I was surprised that there was no changing table in the restroom. I guess that means that families with babies aren't welcome here. Overall, not a great experience. Hopefully it'll get better over time. read more

I love this new rooftop restaurant. Pasadena very much needed this and with an amazing view of the mountains. The food was absolutely amazing especially the salmon crudo. It was to die for.

Always checked up on us and made some great recommendations. I will definitely be a regular here read more

2nd time dining here. Our server started out strong: was very polite and professional. However, as the dinner went on, the service progressively got worse. To the point where she didn't say one word to us/didn't acknowledge us after paying our bill. After she took our order, we barely saw her. We had to ask her co-waiter/assistant repeatedly for water refills. Was it because we were a party of 6 and gratuity was already included? We really hope this restaurant fixes their poor service. The ambience is beautiful. read more

Osa Rooftop is such a great find. The rooftop setting offers a beautiful view, and having a dedicated entrance makes it feel even more special. From the moment we arrived, the service was excellent with a warm, friendly hostess and an attentive, thoughtful server throughout the meal. The food was creative and absolutely delicious. Who knew beets paired with Greek yogurt could be so flavorful? And the artichoke and green chile dip was a fantastic twist and a fresh, exciting alternative to the usual spinach and artichoke dip. A wonderful overall experience with great vibes, great service, and memorable food. We will definitely be back. read more
