I've been here a few times. I always enjoy it. It's a great location with 2 floors and a rooftop seating. The servers are always real nice. The beer selection isn't bad. The food is always tasty. My favorite part is grabbing a drink on the rooftop...always fun.
The only reason it's not 5 stars is that's there is nothing about Six Penn that really stands out as extraordinary. It's a great, above average, spot for a reasonable price.
