All-you-can-eat Sunday brunch buffets aren't about precision-cooked food; they're about luxuriating in horn of plenty-type decadence for a few hours before the weekly grind begins again. And Nikki Beach — with its bed tables and private dining (or whatever) teepees in the oceanfront dunes, not to mention its famously hard-partying patrons and equally famous mojitos — so defines decadence that it's hard to believe the word existed before the place did. So it's good to know that after about a year's experiment with a normal, choose-one brunch menu, the more fitting too-much-ain't-enough beachfront buffet is back. You've got your sweets: mini croissants, Danish, muffins, bagels, and so on, plus a full array of desserts, including lovely fruit tarts, flan, and cr?me brûlée. You've got your salad station, featuring fruit and Caprese salads (both the fruit and the mozzarella fresh), several prepared mixed salads, crudités or greens with a choice of dressings, and a selection of cold cuts and cheeses. There's sushi — tuna, salmon, and vegetable makis, and good seaweed salad and edamame to go with it. There's even breakfast food — scrambled eggs, French toast, and omelettes that are custom-prepared, with diners' choice of smoked salmon, cheese, ham, mushrooms, and much more. There are bigger brunch buffets in town, but at $29.95, this one's less than half the price of the biggest ... and, considering the setting, more than twice as suitable for a self-indulgent Sunday.
