If you are on the Upper West Side and want a generic good diner, Utopia will fit the bill. It has been around for decades and offers classic fare. The prices are reasonable for Manhattan, which is to say not cheap, but the service is efficient and the Amsterdam location is convenient.
If you’re in a rush or just want eggs on a Sunday morning, this could be a good place.
Go with friends for a bite, by yourself to sober up in the morning or because you want something casual by Central Park without breaking the bank.
