Question: what is the difference between the upper east side and the lower east side?
Answer: The biggest difference between the Upper East Side and the Upper West SIde is the size: while the UWS extends to 110th St., the UES ends around 96th. St, where East Harlem takes over. That makes it less than two miles long, but it is about a mile wide, which is part of the reason there's a new subway being built .
