Click's is a great place to hang out after work. Go in and grab a beer (drafts are only $3); set up at a table with your buddies; and try to determine which of you is the best, or least-bad, pool player. Some people might be turned off by the dive-bar nature, but those people obviously don't belong in Click's, because good billiards = dive bar. If you are too pretentious to drink beer and shoot pool without thinking, "This place is a little damp," then, please: Leave. The rest of us will continue on, drinking and eating popcorn with too much butter, and shooting pool until it's time to go out to the clubs.
