I would give Six Penn a 3.5 if I could. Went here immediately after Eleven so am comparing it to that. The place (on a Thursday evening) was packed, then everyone cleared out right about the time the local theater was starting up.
The menu has some interesting items and all were quite good (buffalo mac and cheese was very creamy but also quite salty/rich. Pork shanks and pork chops were nice and juicy. The service was interesting - tried to subtly upsell us on the soups and salads (not included.)
Overall a solid option particularly if you're downtown for a show but be prepared to pay for it. On a side note, they have a dessert that appears to be a tower of cotton candy on top of whoopie pies - this kept appearing on all the tables around us.
