For anyone reading the reviews, keep in mind that the old building was demolished (to make room for condos) and rebuilt a little south of its previous location in 2011 so old comment's about the bathrooms, interior, etc. can be ignored. Also a lot of the staff has changed as there were several months of no business while constuction was going on.
There are some excellent waitresses that work at Jamesons. Our all time favorite Lyndsay has moved on after working five years at Jamesons while attending Mount Royal, but there are others (Prysilla) who recognize us and ask us if we want our usual drinks, etc. Occasionally there will be someone new that's learning the ropes, but generally the service is very good to excellent.
We've been going to Jamesons for years and we've always been happy with the service, food, music (perfect to our taste) and tv coverage (who needs cable/satellite for sports anymore? just go to Jamesons!)
There are a lot of specials that shouldn't be ignored. Wings are on special Sundays and Wednesdays and don't miss Tuesdays for the dry ribs (15 for 15 cents each with many flavors!). Check the menu or the display board as you come in. If you like fried pickles, they have the best in Calgary so far as I can tell.
Prices might be a little higher than other places, but the quality of the food and service makes it worth while.
