Anyone know the dress code here?

Does anyone here generally know what the dress code is? Either based on what you were wearing or what you saw other people wearing.

I was thinking of making the long trek here soon since it seems fun, and I was wondering if they have a strict dress code like other clubs, or maybe not so much since they're a little more hole in the wall.

If not, then I might wear some looser pants (polo sweats that look nicer but are very comfortable), but not if it gets me kicked out.
