Overview
Restaurant 604 is a waterfront Hawaiian-fusion bar and grill in the Pearl Harbor area of Honolulu, aimed at travelers who want a meal with a view as much as a meal itself. The official site describes it as a relaxed, island-inspired place with live music, Pearl Harbor views, and a laid-back surf vibe; Google’s listing matches that general identity and places it at 57 Arizona Memorial Dr #108 in Honolulu. (restaurant604.com)
For a traveler, the main appeal is the combination of location and broad, easygoing menu: it is not a special-occasion fine-dining room, but a scenic, casual stop that works well before or after Pearl Harbor sightseeing. The biggest reason to keep it on a shortlist is that it offers a dependable “Hawaiʻi-style crowd-pleaser” experience rather than trying to be narrowly niche. (jbphh.greatlifehawaii.com)
Cuisine & Specialties
Restaurant 604’s menu sits in the Hawaiʻi fusion lane: American and Pacific Rim dishes, comfort-food classics, and local favorites built around seafood, pork, chicken, and brunch staples. The menu is broad enough to cover lunch, dinner, brunch, and happy hour, with a lot of familiar traveler-friendly choices rather than a highly specialized culinary program. (restaurant604.com)
Notable items supported by the menu and other sources include kalua nachos, poke nachos, crispy shrimp, crispy pork belly, pupu steak, fish tacos, fish & chips, ahi katsu, macnut mahimahi, loco moco, and brunch items such as guava pancakes, ribeye hash, benedicts, kalua pig benedicts, and cinnamon bun pancakes. The official site and Great Life Hawaiʻi both emphasize weekend brunch and hand-crafted cocktails, and the venue also highlights live-music happy hour. (restaurant604.com)
- Overall menu style: Hawaiʻi fusion / Pacific Rim-American comfort food, with seafood, pork, burgers, salads, brunch plates, and cocktails. (restaurant604.com)
- Notable dishes / specialties: kalua nachos, poke nachos, crispy shrimp, fish tacos, fish & chips, ahi katsu, macnut mahimahi, loco moco, guava pancakes, ribeye hash, and benedict variations. (restaurant604.com)
- Price expectations: Google lists it at price level 2, which usually means moderate rather than cheap or upscale; the menu supports that with many mains and brunch items in the mid-teens to low-30s range.
I need to correct one item above: because I am not allowed to invent a source citation, I should state the spend expectation directly from the evidence instead. The menu shows most starters around the high teens, lunch/dinner mains mostly in the high teens to low 30s, and Google’s price level is 2, so travelers should expect a moderate bill rather than a budget one. (restaurant604.com)
- Dietary usefulness / limitations: There are useful seafood, salad, and vegetable options, plus brunch choices that can fit mixed groups. But this is not a strong vegetarian- or vegan-forward restaurant; many signature dishes center on fish, pork, chicken, eggs, dairy, or rich sauces. The menu also includes the usual raw/undercooked food safety warning. (restaurant604.com)
Notable Features & Ambiance
The setting is the big differentiator here: an open-air waterfront room beside the USS Arizona Memorial / Rainbow Bay Marina area, with Pearl Harbor views and a deck-like, casual atmosphere. The overall experience is designed around lingering over a view, live music, and drinks rather than a quick anonymous meal. (jbphh.greatlifehawaii.com)
- Service model and seating style: Casual dine-in restaurant with reservations/waitlist options, takeout, delivery, and private events; the site also mentions parties of 10+ receiving an automatic 18% gratuity. (restaurant604.com)
- Atmosphere and decor: Relaxed, surfy, open-air, waterfront, with live local music and sunset-oriented appeal. (restaurant604.com)
- Practical features: Good fit for brunch, happy hour, post-sightseeing meals, and group gatherings; the official site also surfaces events and private-event capability. (jbphh.greatlifehawaii.com)
- Best fit: Travelers visiting Pearl Harbor who want a scenic, easygoing meal with broad menu appeal and a little atmosphere. (jbphh.greatlifehawaii.com)
- Weaker fit: Visitors seeking a quiet, intimate, or highly refined dining room; people especially sensitive to noise, crowding, or a tourist-heavy setting may prefer elsewhere. This is an inference from the live-music / casual waterfront positioning and traveler review patterns. (restaurant604.com)
History & Background
Restaurant 604 opened in 2016 in the former Schooners space near the Arizona Memorial, and the name comes from the building number, according to owner Donovan Maples in local coverage at the time. The current official site continues to position it as the first 604-family location and notes the restaurant was established in 2016. (hawaiinewsnow.com)
That backstory matters because it explains both the name and the identity: it is not an old legacy institution, but a comparatively newer hospitality concept that leaned into the Pearl Harbor location, local music, and an approachable fusion menu from the start. (hawaiinewsnow.com)
Review Sentiment Snapshot
What People Love
Reviews and traveler-facing summaries consistently praise the view, the relaxed atmosphere, the live music, and the fact that it feels like a worthwhile stop after Pearl Harbor sightseeing. Commonly mentioned strengths include generous portions, good cocktails, and a menu that feels broad enough for mixed groups. (restaurantji.com)
Common Gripes
The weaker signals are not severe, but they are recurring enough to matter: some diners report uneven service, and the place can be busy, lively, and a little noisy. Price is also sometimes described as comparable to Waikīkī, which is not a complaint about quality so much as a reminder that the setting and view are part of what you are paying for. These downside signals are supported, but they look mixed rather than dominant. (restaurantji.com)
Practical Visitor Tips
- Hours on the official site and Google are broadly aligned: generally 10:30 AM–9 PM Monday through Thursday and Sunday, 10:30 AM–11 PM Friday, and 10 AM–11 PM Saturday. Great Life Hawaiʻi’s page shows older or different hours, so the restaurant website is the better current reference. (restaurant604.com)
- The restaurant appears to support reservations, online waitlist, takeout, and delivery; for larger groups, the site notes an automatic 18% gratuity for parties of 10 or more. (restaurant604.com)
- This is a strong candidate for a Pearl Harbor day trip meal, especially if you want a scenic lunch, brunch, or early dinner without leaving the area. (jbphh.greatlifehawaii.com)
- Expect a casual, high-traffic setting rather than a quiet one, especially around sunset, happy hour, and live-music times. (restaurant604.com)
- The menu is broad, so it works well for groups with mixed preferences; seafood-forward and island-fusion dishes are the safer bets than anything ultra-specialized. (restaurant604.com)
Verification Notes
- Official name: Restaurant 604. Address and phone on the official site currently match the Google identity, though the official contact page uses 57 Arizona Memorial Dr #108 and the Great Life Hawaiʻi/JBPHH page uses Bldg. 604, JBPHH, HI 96860. This looks like suite/billing-style address formatting rather than a true conflict. (restaurant604.com)
- Phone number conflict: Google shows (808) 431-5224, while the official contact page and the JBPHH directory show (808) 888-7616. This is a meaningful discrepancy and should be treated as an unresolved drift signal until directly confirmed. (restaurant604.com)
- Operational status appears current/operational on Google and on the active official site. (restaurant604.com)
