Caffeine, booze, cupcakes, Italian: the food groups of the NYC diet. You spaghetti your way through life. Was there really a time before people ate the magic from the boot? Well, someone had to do crafty PR to get those pasta recipes across the Alps: Pellegrino Artusi, author of legendary 1800s cookbook The Science of Cooking and the Art of Eating Well. It’s in his honor that you’ll be eating at L’Artusi, opening tomorrow in the West Village. The sophomore effort from the pack-’em-in guys behind Dell’ Anima features a seasonal Italian menu — gnocchi, spaghetti and meatballs, chicken cacciatore, braised beef cheeks — along with traditional, artisanal wines from Italy and NY State. (Trying times require comfort food and soothing booze.) The midnight blue bilevel space includes separate bars for drinking, cheeses, and crudo. The essential courses, you might say. L’Artusi, 228 West 10th Street, between Bleecker and Hudson Streets (212-255-5757).
