Bars and nightclubs
Foundation
York st. in the alley behind e18hteen. restaurant during the week that is open for lunch and dinner. excellent food and one of the only restaurants in ottawa to serve fondue. on friday and saturday nights it transforms into an upperclass nightclub. dress to impress, no logos or running shoes, and be prepared to spend a few bucks on drinks.
Zaphod's Beeblebrox
York st next to dominion. alternative rock/new age punk, hip-hop nights on thursday. recently short-listed in cbc radio 3's "searchlight: the best live venue in canada" competition. and yes, they do offer a drink they call a "pan-galactic gargle blaster"!
The Standard
360 elgin st. a restaurant during the day, pumping club/lounge at night. the standard is popular thursday, friday and saturday nights with a different style of music each night. friday is excellent old-school and modern hip-hop/r&b while saturday is a little of everything. excellent beer tap selection and daily drink specials.
Pubs
Minglewoods
A great place to drink for cheap! Pitchers of domestic and premium beers are priced under $11 so if you're on a budget this is the place to go. It is close to the University of Ottawa so many students frequent Minglewoods between or after class. There is a good selection of pub fare, also for reasonable prices. On the weekend there is a packed dance floor on the second level.
The most popular bar areas are in the ByWard Market, along Wellington Avenue in Westboro and along both Elgin Street and Bank Street between Somerset and Gladstone in the Centretown area. There are pubs and bars scattered throughout the city as well.
You can also take a small trip over the Ottawa river to Gatineau. Bars on Ottawa side close at 2:00 AM, though the province of Québec has a last call of 3:00 AM, an exception is made in Gatineau where bars also close at 2:00 AM.
Note that smoking is not permitted in Ontario or Quebec restaurants and bars. A new bylaw, which came in force in 2012, also bans smoking on the patios of bars in Ottawa.
