A few reasons I did not attend Cask Days, in spite of the plethora of exciting beers available:
First off, it costs between $35 and $65 depending on how many sessions one chooses to attend.
Tokens are $2.50 each. A five ounce pour is one token and for imports it costs two tokens. This works out to $20.00 for a pint of an imported beer.
It's all to rich for me but I gather the place is packed (another reason against in my view) so they are managing very well without me and my wish for Cask Days is that it continues to flourish.
