Went to Six Penn with a small group. The menu was helpful by indicating what is gluten free. We had the prosciutto pizza (with GF crust) --everyone enjoyed it. They have a huge wine selection. Staff were friendly and quick to serve. I got the grilled NY strip - I definitely recommend it! The mashed potato side was AMAZING. My husband got the espresso-cured top sirloin and was not pleased. He asked for it to be cooked medium and got it back completely cooked through and tough to eat. He returned it and the second dish he got was just as bad. Prices are pretty high, but serving sizes were good.
