The Keg Steakhouse and Bar - Edmonton

This is my absolute favourite restaurant. The food is perfect every time, and you can be sure if you didn't like anything they'll make amends in a big way. Wait staff is VERY knowledgeable and courteous. The menu is mostly steak and seafood. Fancy tables, dim lighting, music is not too loud, the available alcohol is very good quality.
Huge lineups on special occasions, several hour wait sometimes, be prepared to sit in the lounge for a while before they find you a table. If you get a seat in the lounge you can be served drinks and even your whole meal there if you so choose.
Expect to pay more than $100 for two people. Appetizers are around $10 and meal items (steak/lobster/etc) are around 30 or 40. Drinks are reasonably priced.
It is open late, but not 24 hours. I've had no problem entering after 10pm and finishing a long meal.
Usually fairly formal attire but we went there with nothing to do on Hallowe'en and nobody gave us any grief over wearing costumes so it's not like there's a dress code.
The menu does not really accommodate children.
I love this place and you will too.
