Numbers aren’t our strong suit, so we’ll keep it to one hand.

1. Pan-roasted croutons tossed in a bag with herbs and fresh Parmesan, cheeses from Poughkeepsie’s Sprout Creek Farm, and brothless French onion soup served in an iron skillet make up Robert Crosson’s upstairs-only menu.

2. Milk Punch (cognac, Jamaican rum, milk) and French toast on a stick at brunch.

3. Trickster cocktails downstairs, like Gourmet Popcorn (corn-infused vodka, salt-and-butter-infused vermouth, and Combier orange).

4. Edison bulbs in canning jars and candelabra-like pipe wall sconces illuminate reclaimed wood benches and tables and salvaged schoolhouse doors.

5. A retractable garage door, late-night hours (till 4 a.m. on weekends downstairs), and more-than-ample space make it the new birthday spot.

It’s slated to open Wednesday — assuming everything adds up.
