Especially the whole chicken. ### juliqnc — 4.3/5 · Mar 3, 2025 This dish we tried was very special. It is "Bai-Top Shells" which is just another word for a Whelk. The flavor was immaculate and is one of the more interesting Korean dishes I've tried. This place is more of a late night karaoke spot, where you can get drunk and spend time with friends, family, or your s/o. The food leans toward the expensive side, but money doesn't matter when you're too drunk to tell. ### user_f056f3 — 5.0/5 · Aug 21, 2025 great food and friendly staff! ### 88tumble — 5.0/5 · Aug 30, 2025 The black bean noodles are a treat you don’t want to miss 💙 The best noodles in the business & a special if you go at night. Definitely try OB square for a great black bean noodles experience!
