Chim’s Thai Kitchen is my go-to place for pad thai in Columbia. Once upon a time, they had three locations — downtown, off Nifong Boulevard and down by the river at Cooper’s Landing. Last fall, I called to to put in my weekly order and the phone rang and rang. No one picked up. I drove to the restaurant, and it was vacant. What was I supposed to do? Where was I supposed to get my pad thai? The other Thai joints had to suffice. I didn’t know where Chim’s went.
