The Rogers Centre (aka Skyome, aka Dome) is a huge part of Toronto's image. This is why I am still upset at Rogers for rebranding the building and selfishly leaving out any trace of "The Dome".
Regardless of the name, sporting events are always such a blast here especially when the roof is open! Sunny days or rainy days, fans and spectators of events can come out and enjoy the day.
For Bluejays games, there is a good selection of foods and drinks. Beer, wine and even coolers I believe are available on the first floor. Make sure not to get ripped of completely from the tall boys ($11.75/500mL) and get a King size bud or bud light for ($14.00/710mL). You can purchase them at vendors on the first level.
Pricewise, everything is marked up atleast 50%. In other words its expensive...either make sure you have eaten prior or be ready to spend.
