We have eaten there at least half a dozen times at this point, though we have never tried to order off the bar and/or lunch menu at dinner. I wouldn't think there would be any issues as the lunch menu doesn't differ (if at all) from the dinner menu. Nor do I think you would have an issue ordering off the bar menu either. Why would they turn away money you know?
If you can get it at the bar, what's the difference of ordering it at a table?
