Sorry I have not had the time to update the dinning section just yet.
Madklubben is one option.
You could also try Den Tatoverede Enke (The tatooed widow) close to Kgs. Nytorv - www.dentatoveredeenke.dk
A typical blue collar place would be a bodega - a bar. Usually with that name and with coloured windows. You will not find any in the center of Copenhagen. But on Amager - the Island your hotel is on - has some. But not around Crowne Plaza (you will make yourself familar with the Metro).

A hot dog is not really a meal - rather a snack. Of course depends on how hungry you are - or how many hot dogs and sausages you want (most hot dog stands have 20 or so different options on sausages - incl 2-3 hot dog varieties. The susages are made of pork - unless stated otherwise. While some locals will certainly have a favourites for most visitors any hot dog stand will do the job.

Elefanten og Musen (the Elephant and the Mouse) at Vestergade 21 close to the Town Hall square is a quite decent low key waterhole. Always a favourite when I take our US friends for a drink. Snaps is the national drink -and if you really want to go local - order a Gammel Dansk for breakfast and buy a bottle of it to take home. We drink it for breakfast on special occastions.
A pint of beer will set you back DKK 30-60 (incl tax - tips not required) - more in clubs.
