The bar is reminiscent of Cheers -- and for good reason -- it opened when that was still fashionable. Dark wood and low light are far from modern.
Edison's is not trendy. It's a fixture and it's a fixture for good reason. The pizza is excellent and the beer is cheap and unpretentious. It's everything you hoped a bar would be when you were younger and there's still nothing wrong with that formula today.
I usually call ahead even when I'm going to eat there as it is not uncommon to have a one hour wait for pizza. It's well worth the wait.
