O'sun Grill

Overview & Vibe

Tucked away on Liliʻuokalani Avenue in the heart of Waikiki, O'Sun Grill offers a refreshingly authentic alternative to the standard tourist-heavy dining scene. This family-owned food truck destination is a local favorite, masterfully blending traditional Hawaiian plate lunch culture with vibrant Vietnamese flavor profiles. The vibe is laid-back and unpretentious, featuring comfortable, casual outdoor seating that allows you to soak in the Waikiki breeze. Whether you are fueling up after a long day at the beach or seeking a satisfying, high-quality meal well past midnight, O'Sun Grill provides a warm, welcoming experience that feels like a true local secret.

Menu Highlights & Must-Try Dishes

The culinary philosophy at O'Sun Grill centers on bold, fresh, and made-to-order plates. Guests consistently rave about these standout offerings:

• Salted Egg Yolk Shrimp: The crown jewel of the menu. These succulent shrimp are coated in a rich, savory, and slightly sweet salted egg yolk glaze that offers a unique umami depth rarely found in casual eateries.
• Honey Coconut Shrimp: A perfect balance of island flavors. The light, crispy coconut batter meets a sweet honey drizzle that provides a tropical crunch with every bite.
• Garlic Butter Fish Fillet: Featuring the catch of the day, this dish highlights local freshness, seared to perfection and smothered in a fragrant, buttery garlic sauce that pairs beautifully with their steamed white rice and mac salad.
• Kalbi Short Ribs: Marinated in a traditional sweet and savory BBQ sauce, these ribs are tender, charred to perfection, and represent the gold standard of Hawaiian plate lunch comfort food.

Insider Dining & Tips

Because O'Sun Grill is a popular late-night staple, expect lines to grow during the 9:00 PM to midnight window. If you want to avoid the wait, aim for a mid-afternoon lunch around 2:00 PM or an early dinner before 6:00 PM. While reservations are not taken due to the food truck format, the service is remarkably efficient for made-to-order food. Bring cash as a backup, though card payments are generally accepted, and don't be afraid to ask for extra sauce—the kitchen is known for its hospitality.

Location & Parking

Located at 140 Liliʻuokalani Ave, O'Sun Grill is just a short stroll from the primary Waikiki hotel district. Street parking in this area is limited and highly competitive; it is strongly recommended to use public transit, a rideshare service, or utilize nearby public parking garages if you are driving. The location is perfect for a pre-beach picnic or a late-night bite on your way back to your hotel room.
