Chicago Polish Bar - Midway Bar - Chicago Tavern - Angie's Bar

I heard recently that Monday, February 2nd, the show that was filmed will air.  There are a few things online about it here, here and here.  It seems that he did eat at Hot Doug's and  Fat Tommy's among others.  I went to Hot Doug's a week ago and left after waiting for just enough to enter the inside and see the cash only sign.  I am sure it is a great place, and I will return, but this an open letter to the Hot Doug's management:
 
Put a cash-only sign in the outside window.  Why is that so difficult?  Many of us don't carry cash because we use our debit cards whenever we can.  Its easier, and very easy to manage your finances that way.  So, accept this fact, that much of the world uses credit/debit instead of cash.  So if you guys refuse to get a machine(we at angies still havent either, probably for the same reasons as you guys), at least put a sign out so that it may save us some time :)
 
And no, we don't have a sign in our window, but we also dont have lines out the door on a daily basis!
