I use to frequent this place on my lunch hour. The last time I went there to grab a quick lunch we were sitting in the booth talking and waiting for the waitress to bring us our order when the person across from me pointed out that there was a roach crawling up the booth next to the wall. I composed myself and used my napkin to squish it. Haven't been back since.
