Brunch in the E70s
Two of the best brunches on the entire Upper East Side may be enjoyed at two restaurants a block apart:
Lenox Room (1278 Third Ave., between 73rd and 74th). It gets very busy, but if you go at noon, you'll be fine. I'd be astonished if you didn't love it.
Tano (1409 Second Avenue, between 73rd and 74th)
The brunch entrées (including soup or salad, juices, champagne, or Bloody Mary) run $12-21, with most well under $20. The place is intimate, friendly, and all around swell.
Hope this helps.
