No, it's a very well established, eclectic and rootsy musical lineup, and a small, but very well known popular music venue. I've been there several times. most recently last winter when my friend's Zydeco band was playing.
I understand how annoying it can be when people are rudely talking during a performance, but to tack on a $250 charge for opening your mouth is extreme.
There used to be a jazz club called Gulliver's in Lincoln Park, NJ. I saw Louie Bellson there once. The owner, an oddball named Amos, had very visible signs on every table sternly warning people not to talk loudly during the performance, but there was no extra "talking charge" tacked on.
Gulliver's went out of business shortly thereafter. I'd hate to see the Turning Point suffer the same fate.
