After shuttering for renovations last month, Williamsburg transplant Planet Thailand 212 has reopened as an outpost of Boyd Thai. All week between 4 and 7 p.m., Planet Thailand owner Anna Popermhen and Boyd owner Amy Moko are celebrating their new partnership by offering three free bottles of beer (Singha, Chang, or Corona) with every prix fixe dinner (beers are $2 with à la cart items). The décor hasn’t changed that much — the large white booths have been replaced, the large bar that centers the room is now dressed with bright red chairs, and the sushi bar has been brought to the front to create a colorful lounge. But according to Moko, the entire staff and menu is new: “We want to really focus on good food and good service. We also lowered the price of the menu.” The $25 prix fixe menu allows a choice of salad (cranberry or mango) or soup (Tum Yum or a Miso); starter (steamed calamari with a chile dipping sauce or Vegetable Duck on pineapple skewers); and entrée (filet of bass grilled with a pear blue-cheese salad, a grilled New York sirloin sautéed with green vegetables and a spinach cream, or a sautéed salmon with sugar snap peas).
