This is a solid lunch spot, but sometimes it's best to have a reservation. Luckily, they use OpenTable, so you can earn some points.
Their specials are usually pretty good, but my favorite here is the Caesar salad with shrimp. It comes with a few anchovies - you can always have them leave these out, but then we may not be friends anymore.
I've also enjoyed the pizzas here.
I'm only rating Six Penn at 3 stars because it's a tad overpriced and because needing a reservation at lunch is kind of annoying. However, if can you plan ahead, I'd recommend it.
