I highly HIGHLY reccomend Silent H, a newish restaurant in Williamsburg (on North 8th and Berry)...where Oznot's Dish used to be.
My boyfriend and I have been there twice in as many weeks and we've gotten out of the restaurant both times for less than 50 dollars (with us both ordering appetizers and a main course...or a lot of tapas).
Not to be missed is the green papaya salad with pork belly and the spicy beef carpaccio.
The decor leaves a lot to be desired...the stools are a little hard on the butt and they took out a lot of the charming things in that space.
Oh! AND THE BEST PART? BYOB!
