Pittsburgh is a better sushi town than Boston
Sure, you can get good sushi if you have a lot of money and, sure, Pittsburgh is inland, but Dave Copeland makes the case that day in, day out, you'll get better sushi there:
The reason Pittsburgh excelled is because it didn’t have the glut of mid-level and hole-in-the-wall sushi places that Boston suffers from. Those places in Boston don’t attract crowds because there are so many to choose from. They do a decent business, but not a brisk business. That means fish seems to sit longer and seems to taste less fresh than it did in Pittsburgh, which is four hours inland.
