Overview
Chubby’s Diner is a casual, budget-friendly diner inside KBXtreme in Kailua-Kona on the Big Island. It’s the kind of place travelers go for an easy, no-fuss meal rather than a destination dining experience: all-day breakfast, plate lunches, burgers, and local comfort food, with bowling, arcade games, and drinks next door or nearby as part of the same entertainment complex. (kbxtreme.com)
The identity is fairly clear and stable: the name, address, phone number, and website all line up with the KBXtreme entertainment center at 75-5591 Palani Rd, and Google still lists it as operational. The main traveler value here is convenience plus a broad local-comfort menu in a lively indoor setting, especially if you want food that works for families, kids, or a late evening stop.

Cuisine & Specialties
Chubby’s sits in the Hawaiian comfort-food / American diner lane. The official menu description says it serves local Hawaiian-style and American comfort cuisine, including appetizers, plate lunches, grill items, fresh fish, soups, salads, and all-day breakfast, plus sweets like soft serve, cookies, churro bites, and banana cheesecake lumpia. The toast menu and local coverage both point to a broad, family-pleasing menu rather than a narrow specialty concept. (kbxtreme.com)
- Overall menu style: casual diner food with a strong local plate-lunch component, alongside burgers, breakfast, and bar-snack type items. (kbxtreme.com)
- Notable dishes/specialties supported by sources: loco moco, chicken katsu, pork adobo, oxtail soup, mixed plate with teriyaki beef/kalbi ribs/Korean chicken, fish and chips, and all-day breakfast items like pancakes or omelets. (toasttab.com)
- Desserts / snacks: soft serve, churro bites, banana cheesecake lumpia, cookies, and other baked goods. (kbxtreme.com)
- Price range / spend expectations: Google lists it as price level 1, and both the restaurant and third-party coverage describe it as a value-oriented spot with “great prices” or “great prices” language. In traveler terms, it should read as low-cost to moderate-cost rather than a splurge meal. (toasttab.com)
- Dietary usefulness / limitations: there is at least one clearly supported vegetarian-friendly option in the local review coverage, which notes Beyond Meat as a loco moco meat substitute. Beyond that, this is still a meat- and carb-forward diner menu, so it looks more accommodating than specialized. (hawaiianislands.com)
Notable Features & Ambiance
Chubby’s is part of KBXtreme, so the dining experience is tied to a bowling/arcade/entertainment setting rather than a standalone restaurant room. The result is a lively, family-friendly, indoor place where noise from the entertainment side is part of the experience, not a side note. That makes it a practical choice for groups, kids, and travelers who want something casual and easy after an activity. (kbxtreme.com)
- Service model and seating style: dine-in plus takeout/delivery ordering is supported; the restaurant is inside a larger entertainment complex rather than a formal sit-down venue. (kbxtreme.com)
- Atmosphere and decor: casual, festive, and a bit noisy because of the adjacent arcade and bowling alley; sources also describe it as family-friendly and a “local getaway.” (hawaiianislands.com)
- Amenities / practical features: bowling, arcade games, sports viewing, karaoke, drinks, and online ordering are all part of the KBXtreme ecosystem. (kbxtreme.com)
- Best fit: casual family meals, late-ish breakfasts, easy dinners, groups with kids, or an indoor stop when you want to combine food with entertainment. (toasttab.com)
- Weaker fit: quiet, romantic, or view-driven dinners; the setting is functional and lively rather than scenic or intimate. (hawaiianislands.com)
History & Background
There is limited deep ownership history in the sources reviewed, but one local review source says Chubby’s has been a “local getaway since 2009,” which suggests it has had a long enough run to become a known Kona comfort-food stop. Beyond that, the main context is its role inside KBXtreme’s broader entertainment complex rather than as a chef-driven standalone restaurant. (hawaiianislands.com)
Review Sentiment Snapshot
What People Love
People repeatedly like the convenience of getting solid comfort food in a bowling-alley/arcade setting, especially for casual family outings. Positive patterns include all-day breakfast, generous plate lunches, local dishes like loco moco and oxtail soup, and the general sense that it is a fun, easy place to eat without paying resort prices. (toasttab.com)
Common Gripes
The main downside is not about the concept so much as the setting: it can be noisy, and it is not the right place if you want a calm or romantic meal. Review evidence for food quality complaints is mixed and not especially strong in the sources found here; the criticism that does appear is more about the atmosphere than a recurring, well-documented menu failure.

Practical Visitor Tips
- Hours posture: Google lists daily service from 9:00 AM to 10:00 PM, with later closing at midnight on Friday and Saturday; Toast echoes that schedule. Breakfast is available all day. (toasttab.com)
- Best time to go: earlier in the day is likely calmer; evenings may be busier because of the bowling/arcade crowd, and Friday/Saturday nights run later. This is an inference from the location inside KBXtreme and the extended hours. (kbxtreme.com)
- Reservations: the sources emphasize walk-in dining and online takeout/delivery more than reservations, so don’t assume you need or can easily make a table booking for the restaurant itself. Bowling reservations are separate from dining. (kbxtreme.com)
- Ordering options: takeout and delivery are explicitly supported through Toast, which is useful if you want the food without staying for the entertainment side. (kbxtreme.com)
- What to order if you only go once: loco moco, oxtail soup, chicken katsu, or a mixed plate are the clearest supported “signature” picks from the available evidence. (toasttab.com)
- Who should choose it: travelers looking for a relaxed, relatively low-cost meal near town with a built-in activity option. Travelers seeking quiet ambience, fine dining, or a polished destination meal should look elsewhere. (hawaiianislands.com)
