Twice a day, every location: the shell ritual. Walk in at 1pm or 1am, grab a slam, and if you can drink it in 60 seconds or less it is a dollar. That is the whole rule.
Tea happy hour, every day 7pm to 9pm. A 16oz tea for $8 (normally $12), in house, 21+ (18+ in Arizona). No special day to remember. Just two hours, every night.
