I think this is a nice addition to Mt. Washington. I live right down the street, and this place is always packed.
For me, the best part of The Summit is the atmosphere. I love how they open all the windows, and it's always just a cool place to be. However, I do think their drinks and food are a bit overpriced. Everything I've tried is good, but because of the prices, I'm more likely to choose somewhere else on Mt. Washington.
