Restaurant 604

Restaurant 604 is a casual waterfront bar and grill in the Pearl Harbor area that pairs broad Hawaiian-fusion comfort food with one of the more appealing settings in the district. It stands out less for culinary ambition than for being an easy, scenic, traveler-friendly stop: the kind of place that works for brunch, lunch, happy hour, or an early dinner after sightseeing. The draw is the combination of Pearl Harbor views, live music, and an approachable menu that leans into familiar island flavors without feeling fussy.

What to order and what the kitchen does best

The menu sits comfortably in Hawaiʻi fusion territory, with Pacific Rim-American comfort food, seafood, brunch plates, and cocktails all sharing space. That breadth is a real advantage for groups, since it gives everyone something recognizably satisfying to choose from. The safer bets are the dishes that lean into local comfort-food identity: kalua nachos, poke nachos, crispy shrimp, fish tacos, ahi katsu, macnut mahimahi, and loco moco all fit the restaurant’s style well.

Brunch is a major part of the appeal. Guava pancakes, ribeye hash, benedicts, kalua pig benedicts, and cinnamon bun pancakes give it enough personality to feel distinctly island-adjacent while still being easy to recommend to mainstream travelers. The cocktail program and happy hour offerings round out the experience, especially if the goal is a relaxed meal with a drink and a view rather than a tightly focused culinary outing.

Expect moderate pricing rather than bargain pricing. This is not an expensive fine-dining room, but it is also not a cheap lunch counter; the setting and the broader menu place it firmly in the mid-range for the area.

The experience: relaxed, scenic, and often lively

Restaurant 604’s biggest asset is its setting. The restaurant is designed around waterfront Pearl Harbor views, with an open-air, surfy feel that makes it easy to linger. It has the relaxed energy of a place built for island afternoons: casual, social, and oriented toward taking in the surroundings as much as the plate.

Live music adds to that personality, especially at happy hour and around sunset. For many visitors, that combination of scenery, music, and easygoing service is exactly the point. It feels like a place where a day at Pearl Harbor can naturally spill into a low-stress meal without leaving the area. The room is also well suited to groups, and the menu’s range makes it especially practical when people want different things but still want to dine together.

The backstory helps explain the restaurant’s identity. Opened in 2016 in the former Schooners space near the Arizona Memorial, it takes its name from the building number and has leaned into the Pearl Harbor location from the start. That origin gives it a sense of place without pretending to be a legacy institution; it is a newer concept that found its personality in the setting, the music, and an approachable island-fusion menu.

Tradeoffs, and who it suits best

The main tradeoff is that Restaurant 604’s strengths are also what make it less appealing to some diners. It can be busy, lively, and a bit noisy, especially during peak sightseeing hours, sunset, happy hour, and live-music times. Travelers looking for a quiet, intimate, or especially refined dining room will probably want to look elsewhere.

Service can also be uneven at times, and the atmosphere is intentionally casual rather than polished. That is not a dealbreaker for the right audience, but it matters if a trip calls for a special-occasion meal with a more elevated feel. Price is another mild caveat: the setting and convenience are part of what you are paying for.

Restaurant 604 is best for travelers who want a scenic, relaxed meal near Pearl Harbor with broad menu appeal, easy brunch options, and a strong sense of local leisure. It is especially useful for families, groups, and visitors who want a dependable place to sit down without overthinking the menu. Those looking for quiet, white-tablecloth service, or a highly specialized culinary experience, will likely be happier elsewhere.
