The Upper Crusts

1. Blue Smoke

116 E. 27th St., nr. Park Ave. S.; 212-447-7733

A sensational Key lime and a first-rate banana cream, plus a pie of the day.

2. Clinton St. Baking Company

4 Clinton St., nr. Houston St.; 646-602-6263

Renowned for their brunch and pancakes, but the pie’s good, too.

3. Kitchenette

156 Chambers St., nr. Greenwich St.; 212-267-6740

The kind of old-fashioned double-crust pie that when left on a windowsill to cool, becomes fair game for hoboes.

4. Pies-N-Thighs

351 Kent Ave., at S. 5th St., Williamsburg, Brooklyn; 347-282-6005

The thigh guy has sold his share of the business, but the pie lady remains.

5. Little Pie Company

424 W. 43rd St., nr. Ninth Ave.; 212-736-4780

The sour-cream apple-walnut is as much a New York classic as a Peter Luger porterhouse.
