Thumbs up on the dinner. Their grilled chicken and the cheeseburger empanadas are standouts . Also, a lot more refined dining environment than the brunch zoo.
I've been there for lobster night dinner. It was fine - no more, no less. Not worth a trip out of your way, but if you're around there anyway, you'll do alright.
I happen to really like the restaurant - for both brunches and dinner. I recommend the duck, potato pancakes, short ribs & mac & cheese (also on their brunch menu).
