Where to eat/drink
Close to the Big Blue Tent...
The closest establishment to the Big Blue Tent and where Devils fans can often be found before and after games is the Harvester located within walking distance of the rink. The website, which can be found HERE gives opening times and directions by car.
Located on the otherside of the large roundabout from the rink is a Frankie & Bennies which can be found HERE, better food than the Harvester for sure, but also more expensive...
In the same general area there is a Mcdonalds for those looking for a quick fix, the signs should be viewable from the link road which will bring you into Cardiff Bay. Also in the same retail park is a Pizza Hut, the website with more details can be found HERE
The Big Blue Tent does serve the usual rink food of hotdogs, although it's wise to prepare yourself both mentally and physically before attempting to eat one.
Further away...
Away from the rink and in Mermaid Quay (the centre of Cardiff Bay) are located numerous bars, retaurants and pubs with too many to list here. The website can be found HERE which will hopefully give a better idea :)
