O'Neil's pub has good food & great atmosphere, so I'd suggest heading there. They do have a bad habit of charging at the door due to the Halloween crowds though...

I also would HIGHLY suggest catching a cab to Hammond Castle in Gloucester if they are doing it up as a haunted house again. Very spooky place!

One last thing... if you happen to run in to Laurie Cabot, tell her Gill from Chicago says hello!
