Oliver & Bonacini Cafe Grill

Last reviewed: August 8, 2026. Business status: Active.

Couples researching Blue Mountain wedding catering can consider two distinct options connected with O&B Café Grill Blue Mountain: direct-to-venue catering across the Georgian Triangle and group dining at the restaurant inside The Westin Trillium House. The official regional catering page confirms an event and wedding menu with plated dishes and food stations, while the restaurant’s event page covers wedding-related meals and private-event configurations.

The restaurant remains listed on Oliver & Bonacini’s current website at 220 Gord Canning Drive in The Blue Mountains. Its official event material specifically discusses weddings, rehearsal dinners, post-wedding brunches and the Westin’s ballroom facilities, providing sufficient evidence for an active profile.

Services and specialization

O&B offers full-service, direct-to-venue event and wedding catering throughout the Georgian Triangle. Its regional page describes wedding menus built around plated dishes and food stations and states that service is available at private residences and venues in the region. The official catering overview also says wedding packages may be tailored to a couple’s style and budget, although the final inclusions require a quote.

At O&B Café Grill itself, the wedding focus is group dining surrounding the main celebration. The restaurant specifically promotes rehearsal dinners, post-wedding brunches and other wedding-related gatherings. Couples seeking a ceremony or reception at the same property are directed toward the grand ballrooms within The Westin Trillium House, where O&B is identified as the exclusive caterer.

Event formats and documented capacities

The restaurant publishes several configurations for smaller celebrations. The Harvest Table seats 12 at one table, the banquette accommodates up to 28, and the rounds seat up to 36. Combined layouts can reach 56 seated guests, while the Lobby Bar is listed for standing receptions of up to 40.

A full restaurant buyout can accommodate up to 130 guests, depending on the date, and a buyout fee may apply. For larger wedding ceremonies and receptions, the event page says the Westin’s grand ballrooms can accommodate up to 400 people. That figure applies to the hotel ballrooms, not the restaurant dining room, and should be reconfirmed against the proposed layout.

Service area and who it may suit

The confirmed catering area is the Georgian Triangle, described by O&B as including the Blue Mountains and beyond. Its regional catering page says the team works at private residences and local venues and identifies a selection of exclusive or preferred venue relationships. Couples should submit the exact venue address before assuming it falls within the workable service area.

The restaurant may suit couples planning a destination-style wedding weekend at Blue Mountain who need a rehearsal meal, family dinner, bachelorette gathering or next-day brunch. The off-site service may be relevant when the ceremony and reception are at another Georgian Triangle venue or private property. The published evidence does not define travel fees, delivery boundaries or minimum guest numbers for every off-site format.

Confirmed strengths and practical limitations

A documented strength is the choice between restaurant group dining, conference-facility private dining and off-site regional catering. The restaurant also publishes capacities for its individual areas, which gives couples a useful starting point before requesting a proposal. Its location inside the Westin may simplify planning for couples already considering the hotel’s ballrooms or guest accommodation.

Practical limitations are equally important. Full buyouts depend on the date and may carry a fee, while conference-facility rentals may also apply. The restaurant does not allow outside food other than celebration cakes or cupcakes. Detailed wedding-menu inclusions, staffing, rentals, service hours, dietary arrangements and off-site logistics are not fully stated on the public pages and need written confirmation.

Pricing

Current wedding pricing is not explicitly published. Although the official pages link to catering and wedding packages, the public HTML reviewed does not provide a complete, current per-person wedding price, minimum spend or total package cost. Couples need a written quote based on the venue, date, guest count, menu and service format.

The restaurant event FAQ does publish some narrower charges. It says alcoholic and non-alcoholic beverages are billed by consumption, plus tax and an 18% gratuity, and that fixed-price per-person bar packages are not offered. It also lists cake plating at 3 per person, cupcake service at 1.75 per person and takeaway containers at an additional 1.75 per person. Confirm the currency, current amounts and whether these charges apply to the proposed event before booking.

Contact and booking

The restaurant’s official listing gives (705) 444-8680 for O&B Café Grill Blue Mountain. Wedding and catering enquiries for the Georgian Triangle are directed to (705) 293-3555 and events@oliverbonacini.com. The official event page also provides a request-information form where couples can identify the restaurant, the Westin, off-site catering or a combination of services.

When enquiring, specify whether the request concerns restaurant group dining, a Westin ceremony or reception, or catering at another venue. Include the event date, estimated guest count, proposed times and preferred dining style. This helps prevent confusion between a restaurant reservation and a contracted wedding event.

What couples should confirm

Ask for a current proposal that separates food, beverages, staffing, rentals, gratuity, tax, venue or buyout fees, cake service and any off-site costs. Confirm which spaces are contractually included, especially if the plan combines O&B Café Grill with a Westin ballroom or terrace.

Couples should also verify the final capacity for their floor plan, accessibility, ceremony and reception timing, menu-selection deadlines, allergy and dietary procedures, bar arrangements, vendor access, setup and teardown responsibilities, parking, accommodation coordination and cancellation terms. For off-site catering, confirm kitchen requirements, power and water access, travel charges, equipment, tableware, waste removal and the exact service boundary.
