Amongst the expensive condos and doctors offices, I was really excited to stumble across the Lexington Candy Shop Luncheonette on the corner of 83rd and Lex. Around since the 1920's, the corner shop looks like something I wish I could find everywhere. Jeremiah's Vanishing New York has a much better write-up on the joint from earlier in the year.
The rest of the block is expectedly plain. Sure, there's a few things here and there, but as I've mentioned numerous times, as one gets closer to Park Avenue the less embellishment and character you're likely to find.
