Directions: There are two parts of the Ore Dock, a downstairs (open during the day) and an upstairs (open during the evening). I didn't scout out the downstairs to see if there were bathrooms, but upstairs, there is a marked gender-neutral bathroom near the marked gender-specific bathrooms. The bathrooms are on the side of the bar island nearest the lake.
Comments: I'm not qualified to say whether the bathrooms are definitely accessible or not, but for folks who need to pee and have some mobility issues that make stairs difficult, you can also access the upstairs via the ramp that connects to the porch on the back side of the bar. Also, I didn't notice that they checked ID during the day, but they do at night! You will probably need to be at least 21 (definitely at least 18) to get in. The upstairs is open from 5p-midnight Thursday through Saturday, and from 5-11p on Sunday, though they just opened and the website says these hours may be subject to change. General hours: they're closed Mondays, open noon-11p on Tuesdays, Wednesdays, and Sundays, and open noon-midnight on Thursdays, Fridays, and Saturdays.
