Goose Island is a former US Craft brewery that was bought by one of he big 3 and started exporting into Canada. This brewhouse is a sort of "pop up" attached to Beir Market and shares a kitchen. So from a food perspective it's decent pub food. You can do better or worse.
The pull here is the wide range of micro brews all done on sight by Goose Island. You can get their normal Honkers and IPA, but your better off enjoying the 10 or so beers made in location. They range from low IBU (bitterness) of 6, a play on a Smokey polish style, to a 65 double IPA called Mantis. The latter, which is also quite boozy, was my favourite. Expect bitter with pineapple and stone fruit. Lots of accessible options and they've really covered all the bases.
I'm a bit of a beer snob, but I enjoyed my flight ($14 for 4 x 7oz). My wife had a bacon poutine that she enjoyed.
Worth a visit.
