Arc Lounge

Arc Lounge is a restaurant and cocktail lounge operating at 140 Slater St. The room combines a full dining service with a lounge and bar area built around a central fireplace, offering a menu built on Canadian-sourced ingredients across breakfast, lunch, dinner and lounge service, along with a cocktail program. It serves both quiet one-on-one meetings and larger group gatherings, a combination that suits its position in the heart of the capital's downtown business and government district.

A neighbourhood built around meetings and stays

A restaurant and lounge attached to a hotel on Slater Street is positioned to answer all three needs without requiring guests to leave the block.

Seasonal rhythms of the capital

A fireplace-centred lounge suits the colder months in particular, giving the room a warm gathering point once winter sets in.

Services Offered at Arc Lounge

Arc Lounge structures its day around four service periods — breakfast, lunch, dinner and lounge — allowing guests to use the space differently depending on the time of day. The kitchen builds its menu around Canadian ingredients, and the lounge complements the food menu with a program of crafted cocktails alongside a selection of Canadian breweries, distilleries and wineries.

Breakfast, lunch and dinner service

The morning menu is aimed at an early start, suited to guests preparing for a day of meetings or travel. Lunch service offers a faster turnaround for those working nearby, while the dinner menu shifts toward a more composed, sit-down experience for the evening. Each period draws on the same commitment to Canadian-sourced ingredients, giving the day a consistent culinary thread from morning to night.

The lounge and bar

This makes the space workable for an after-work drink, a small social gathering, or a quiet moment between a hotel stay and an evening appointment.

Group gatherings and quiet conversations

The layout is built to handle both ends of the spectrum: intimate conversations for two, and larger group gatherings that need more room to spread out. That flexibility matters on a street where the same evening might bring a small business dinner and a larger delegation marking the end of a conference day.

A restaurant that builds its menu around Canadian producers is, in practical terms, also a small contributor to the wider circuit of Canadian food and drink suppliers — the farms, breweries, distilleries and wineries whose products reach the table through kitchens like this one. In a city where much of the downtown core is shaped by government offices and national chains, a hospitality business that commits to sourcing its ingredients and drinks from Canadian producers plays a distinct role in keeping some of that spending inside domestic supply chains rather than importing.

That role extends to the immediate neighbourhood as well. In a downtown core built largely around daytime office activity, a restaurant and lounge that stays open into the evening helps keep the area active outside standard business hours, which in turn supports the smaller shops and services that share the same streets.
