When I first started carrying it is really weird. It feels like you have a sign on your side that says "I'm carrying a gun". You feel the need to check to make sure you have it concealed well and no one's going to notice it. After a while it feels like just another piece of your daily equipment; keys, wallet, phone, etc. Sometimes I don't even remember it's there, but I know I would if the occasion to use it would arise.
Although to answer your question, everywhere that's legal. Soon, hopefully, I'll be able to actually go to a decent restaurant to eat even as long as Senate Bill 239 is passed.
Also, if I don't see a sign posted on the front door and it's noticeable, then it's not a legal sign. They can ask you to leave, but if no one notices your weapon you'll be fine. Just like Tuttle Mall. They have signs posted on the foodcourt doors and some main entrance doors, but if you enter at Macy's or Sears there are no signs making it legal for you to be able to carry throughout the mall. Of course you shouldn't admit that you know the doors at the foodcourt have signs, in that case you could be charged with trespassing.
