Don't ask me. I'm not smaht enough.
But if I was smart enough, I'd go with Soup Burg on Lexington, between 76th and 77th. At one time I kept an office in that neighborhood, I ate their almost every day...twice!
To this day, it's my favorite burger in the city, with Jackson Hole (Columbus Avenue and 85th Street location) coming in a not-too-distant second. Jennifer Aniston worked there as a waitress. I'm told she was a very hard worker.
3rd goes to Veleska, the Ukrainian joint on 2nd Avenue and 9th Street. Unbelievable portions, and great food. Those Eastern Europeans really know from breakfast.
