After all that turkey, we were ready to stuff our face with something non-pilgrim related this weekend. Enter Mercer Kitchen, the still-hot, subterranean spot that's located conveniently adjacent to SoHo's main drag of shops. After we worked up an appetite buying gifts, we dropped by for a beverage and some snacks. It's too bad the folks at Plymouth Rock didn't have the peekytoe crab crostini during their first holiday meal, we'd be happy to scarf sweet crab meat off the crispy toast each year, especially with a squeeze of the lemon that was served alongside the dish. There's even a taste of fall thrown in - the bread is smeared with some roasted kabocha squash for an earthy kick. True, this may never become an actual Turkey Day tradition, but a holiday-shopping-season ritual? You heard it here first, folks (99 Prince St.; 212-966-5454).
