Pubs have Atmosphere, Service and Food too!
Atmosphere: The Old Dublin is a pub's pub. Everything wood, everything with purpose - you walk in you know you're in a pub. Comfortable and in the middle of the downtown core, a great place to meet with friends to watch the game (any game).
I will go out on a limb here and say that the days of the Old Dublin may be numbered (along with other places in that area) as a huge and very posh condo complex is being built right next door. This may hark the advent of more upper-end type dinning locations to accommodate the new residence.
Service: The Staff works hard, so much so they are certainly pushed to the limit on busy nights - but they still maintain composure. The staff tend to be a little older (i.e. not of the University crowd) and some have been at the Old Dublin for quit some time, and thus give the place a good sense of continuity. No complaints whatsoever.
Food: Pub food served in a pub way - plain and simple. Hit and miss sometimes - but it doesn't pretend to be anything it isn't. Surprisingly - because the cook is Indian - the old dublin has some items on the menu that may surprise you!
Fun place.
