Picket Fence just opened last week in the space that used to be Rug-B, on Cortelyou between Argyle and Rugby. I live within walking distance so I've already eaten there twice. The first experience, on a Saturday night, was very positive. However a return visit on Wednesday night was disappointing (maybe the chef was off that day?).
On the first weekend the place was packed and there was a short wait for a table. Steak and lamb (special) were both delicious, good quality meats cooked with a delicious glaze or crust that added to the flavor. Salad ingredients were very fresh but a bit plain and unimaginative.
On the second visit the food did not taste as fresh, like it had been prepared too long beforehand. Steak was undercooked and gamy-tasting, turkey meatloaf was barely room temperature. After reheating the meatloaf was quite good and the corn chowder soup special was the highlight of the meal.
Initial indications are mixed, but promising. The menu needs to be developed a bit, there are currently very few appetizers to choose from. I hope they are able to improve on the quality and consistency because the Ditmas Park neighborhood could really use a good bistro type restaurant.
They do not have a license to serve wine yet, but you can BYOB from the liquor store near the Q train.
