Most people seemed to have reservations. I wondered if I could get in a bit early, but they seat you exactly on time after clearing the previous reservation slot, so I'd recommend arriving right at your reservation time! ![OSA Hannam ground floor hall interior](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-04-2w7y2-900.webp) ![OSA Hannam terrace seating and glass-walled rooms](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-05-wogyk-900.webp) The ground floor has a spacious, atmospheric hall along with terrace seating. What especially caught my eye on the terrace were two glass-walled rooms that felt private-ish but not quite haha. The 2nd floor operates as private rooms, so if you're coming for a blind date or a gathering, I'd recommend booking a room too (minimum spend and room charge apply separately)! ## What's on the menu? ![OSA Hannam menu, appetizer page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-06-7suq5-900.webp) ![OSA Hannam sashimi and sushi menu page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-07-1tsa7-900.webp) ![OSA Hannam robatayaki menu page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-08-13ork-900.webp) ![OSA Hannam fried and braised dishes menu page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-09-gcqvv-900.webp) ![OSA Hannam pasta and hot pot rice menu page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-10-5lk2s-900.webp) ![OSA Hannam hot pot menu page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-11-x4frj-900.webp) ![OSA Hannam menu page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-12-1vp26-900.webp) ![OSA Hannam dessert menu page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-13-2hlo4-900.webp) ![OSA Hannam menu, last page](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-14-zym7i-900.webp) Looking at the menu was genuinely surprising — from simple appetizers to seasonal sashimi/sushi, robatayaki, fried and braised dishes, meal items (pasta and hot pot rice), hot pots, and even desserts! It was such an insane range that I thought 'wait, they do ALL this at one restaurant?' — a real Hannam-dong izakaya haha. ![OSA Hannam wine, sake, and whiskey drinks menu](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-15-1hk10-900.webp) The drinks menu is also diverse — wine, sake, whiskey, and more — and corkage is available too (₩60,000 per bottle for wine/sake, ₩120,000 for whiskey), just FYI! ## The food: sweet potato chips, hanwoo sirloin steak, uni pasta ![Complimentary sweet potato chips at OSA Hannam](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-16-kuwvc-900.webp) ![Plate of crispy sugar-dusted sweet potato chips](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-17-vmm0h-900.webp) ![OSA Hannam table setting with starter snack](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-18-1yxrk-900.webp) Once you order, you get crispy sugar-dusted sweet potato chips as a free starter — and honestly, these are a real treat haha. But seriously, it would've been a disaster if these hadn't come out... The food took almost 30 minutes to arrive that day, maybe because orders were backed up. If it weren't for the sweet potato chips, I might've died of anticipation waiting haha. ![Hanwoo sirloin steak table setting at OSA Hannam](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-19-j4il6-900.webp) ### Hanwoo sirloin steak (₩58,000) My companion was craving meat, so we ordered the hanwoo sirloin steak (₩58,000)! Honestly, to me and my big-eater companion, the portion looked slightly small haha. But hey, this isn't just any hanwoo — it's '1++ hanwoo sirloin'!! ![Cross-section of the 1++ hanwoo sirloin steak](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-20-gzwsj-900.webp) ![A well-cooked bite of hanwoo sirloin steak](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-21-1be27-900.webp) It was cooked just right and tasted good, and it was great to enjoy purely for the vibe too!! A steak in a great-atmosphere Hannam-dong terrace dining spot tastes like success haha. ### Bonus: the truffle hanwoo sirloin jjapaguri is actually the real deal Looking at reviews after my visit, the 'truffle hanwoo sirloin jjapaguri (black bean noodles, ₩39,000)' is apparently super popular?! The steak portion on top is generous, and it comes with a truffle-scented jjapaguri plus tasty pa-kimchi (green onion kimchi)!!! Talking about value in Hannam-dong is kind of funny haha, but the truffle hanwoo jjapaguri really is the ultimate value-for-money menu item haha. I'm usually pretty deliberate about my choices, but my pick that day was a bit of a letdown (should've gotten the jjapaguri!! haha) — if you're going, definitely try the hanwoo jjapaguri!!! ![Uni butter garlic pasta at OSA Hannam](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-22-1iti4-900.webp) ![Visual of butter garlic pasta topped with uni](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-23-9up3u-900.webp) ### Uni butter garlic pasta (₩35,000) After going back and forth, I picked something I hadn't tried elsewhere — the uni butter garlic pasta (₩35,000)! Deep, rich butter garlic-flavored pasta topped with nutty uni (sea urchin) — a visual win right off the bat!! ![Uni pasta mixed and served with garlic scapes](https://img.superchart.com/images/osa-hannam-sirloin-steak-uni-pasta/osa-hannam-sirloin-steak-uni-pasta-24-5kayj-900.webp) Mixing the uni all through and taking a bite with the garlic scapes, it was savory and salty with a nutty richness, and the crunchy garlic scapes made it perfect to pair with wine or sake — exactly right for a Hannam-dong bar!!! ## Who should visit OSA Hannam My menu choices weren't perfect!!! (The steak was good too, but the jjapaguri is such a steal haha) Still, the atmosphere was so good that I had a great meal overall!! - Unbeatable terrace vibe: with this cool weather, visiting as a Hannam-dong date spot means the atmosphere does all the work! - Convenient parking: a valet booth right in front makes driving there very easy! - Wide-ranging kappo menu: from sashimi to 1++ hanwoo to pasta, the options are broad! - Visiting tip: serving can take a while, so it's best for people who want to relax and chat & next time, definitely try the truffle hanwoo jjapaguri! ## Where it is - OSA Hannam (오사 한남) - 61-1 Hannamdaero20-gil, Yongsan-gu, Seoul, South Korea - 서울특별시 용산구 한남대로20길 61-1 - 37.5350593, 127.0103581 - Google Maps: https://www.google.com/maps/search/%EC%98%A4%EC%82%AC%20%ED%95%9C%EB%82%A8/@37.5350593,127.0103581,17z --- Superchart · https://superchart.com/en/@golmok-glass/osa-hannam-sirloin-steak-uni-pasta/ · https://superchart.com/llms.txt
