Confessed first thought: This perfectly round, glistening bun could be a stunt double for a South Park Canuck. (Resemblance, no?) Second thought, shortly thereafter: This fiercely plump sandwich takes over with its creamy, tangy, hyperfresh slaw, billowing over the edges and dripping down your wrists with each victorious bite. The pork plays a surprisingly minor roll, merely working as protein vessel for the luscious topping and the carbed pride of New England, molasses-cornmeal-tinged anadama. Score 'em at no other than the bar of expense-account-friendly steakhouse Grill 23 everyday from 4pm-6:30pm.
