2hr wait at 5:30pm in tacoma (72nd st./ I5)
edit:
I never had their chicken before and would have walked out -- but the room full of people waiting were all good natured and friendly, so I stuck it out thinking it must be an amazing deal for a whole room to be generally happy waiting 2hrs for chicken. Every time someone's ticket number was called, it felt like they won the lottery.
The chicken was much better than I remember as a kid from KFC -- but I don't think it was worth the wait. I'll skip it next time, or use the wait time to shop at the Sports Authority, which is in the same parking lot.
I spoke to a lady while waiting and she said they ran the same deal about 6mo's ago -- and there was hardly anyone there. So I guess their advertising was a success.
