Hawaiian plate lunch is a cuisine built on soy sauce, mayonnaise and panko, which makes Ono Hawaiian BBQ a straightforward menu for some allergies and a difficult one for others. This page walks the menu allergen by allergen, and is clear about where the answer is honestly uncertain.
Gluten — the hard one
Gluten is the most significant restriction here, and the reason is the sauce base. The house Hawaiian BBQ glaze is built on soy sauce, and conventional soy sauce is brewed with wheat. That puts gluten in the glaze on Hawaiian BBQ Chicken ($12.49), Hawaiian BBQ Beef ($12.99), Teriyaki Chicken ($12.49), the kalbi marinade on Kalbi Short Ribs ($16.49), and the teriyaki glaze on the Spam Musubi ($6.49).
Add to that everything panko-breaded or battered: Chicken Katsu ($12.49), Crispy Shrimp ($12.99), Island White Fish ($12.99), the Crab Rangoon ($4.49) wrapper, and katsu sauce itself, which is typically wheat-containing. The Macaroni Salad is wheat pasta by definition.
What is left is short but real:
- Grilled Chicken Breast ($12.49) — unsauced white meat, the single best starting point.
- Kalua Pork with Cabbage ($12.99) — salt-seasoned pork and steamed cabbage, no glaze.
- Steamed Rice ($2.99) and Fresh Mix Salad ($4.49) — order the dressing on the side.
The essential caveat: this is a fast-casual kitchen with shared fryers and shared grill surfaces. These items are lower-gluten by ingredient, not certified gluten-free by preparation. For celiac disease rather than a preference, speak to the restaurant directly.
Egg and dairy
The macaroni salad on every single plate is mayonnaise-based, so it contains egg. There is no way to have a standard plate without it arriving — ask for it left off if egg is the issue. Grilled Spam & Eggs ($11.49) is obviously out.
Dairy is comparatively rare on this menu, which surprises people coming from mainland barbecue and its mac-n-cheese. The clear exception is Crab Rangoon ($4.49), which is cream cheese in a fried wrapper. Batters and breading may contain milk derivatives, so confirm at the counter.
Shellfish and fish
Three items to know: Crispy Shrimp ($12.99, or $8.49 as an appetizer), Island White Fish ($12.99) and the Seafood Mix ($14.49), which combines both. The Shrimp & BBQ Chicken, Island White Fish & BBQ Chicken and Shrimp & Island White Fish combos at $13.99 each carry the same exposure. Crab Rangoon commonly uses imitation crab, which is fish-based.
The bigger issue is the shared fryer. Shrimp, white fish, katsu and rangoon all come out of the same oil, so a serious shellfish allergy should treat every fried item as cross-contaminated — including the chicken katsu. Stick to the grilled plates.
Soy, sesame and nuts
Soy is unavoidable in anything glazed — it is the backbone of the BBQ, teriyaki and kalbi marinades alike. Sesame appears in the kalbi marinade specifically, alongside soy, sugar and garlic. Tree nuts and peanuts are not characteristic ingredients anywhere on this menu, which makes it one of the safer fast-casual options for nut allergies, though shared-kitchen caveats still apply.
Keto, low-carb and vegetarian
| Diet | What works | Verdict |
|---|---|---|
| Keto / low-carb | Grilled Chicken Breast or Kalua Pork, no rice, no mac | Possible but awkward |
| Gluten-avoiding | Grilled Chicken Breast, Kalua Pork, rice, salad | Workable |
| Vegetarian | Fresh Mix Salad, Steamed Rice, Macaroni Salad | Limited |
| Vegan | Fresh Mix Salad, Steamed Rice | Very limited |
| Nut allergy | Most of the menu | Generally fine |
Keto is a fight against the format itself — two scoops of rice is roughly 400 calories of pure carbohydrate, as the Ono Hawaiian BBQ nutrition guide sets out. Ask for the plate without rice or mac and you are essentially buying grilled protein at plate prices.
Vegetarians face a genuinely thin menu. There is no dedicated vegetarian plate. The workable meal is Fresh Mix Salad ($4.49) plus Steamed Rice ($2.99) plus Macaroni Salad ($4.49) — and note that the mac salad is not vegan, because mayonnaise. Everything else on the Ono Hawaiian BBQ menu is built around a protein.
How to ask
Order at the counter, name the allergen rather than the dish, and ask about the fryer specifically — it is the single biggest source of cross-contact here. With roughly 90 restaurants, ingredient sourcing and preparation practice can vary between locations, so confirm at the store you are actually eating at rather than relying on a general answer.
