The invention relates to a dinnerware, in particular to a bubble-free quantity-limiting wine cup. The wine cup is composed of a cup body and a stream guidance plane. The stream guidance plane is arranged in the cup body and forms a whole with the cup body. The stream guidance plane is composed of a slant plane and a cambered surface. The top edge of the slant plane is connected with the cup mouth, the lower edge of the slant plane is contacted with the cambered surface, the slant plane and the vertical direction form an included angle of 10 degrees. The distances from the radius of the cambered surface and the circle center of the cross section of the cambered surface to the cup bottom are both 2/3 of the inner diameter of the cup body, and the circle center of the cross section of the cambered surface is located on the inner wall of the cup body. With the wine cup of the invention, impact of liquid to the cup bottom when beer is poured is greatly reduced; as a result, bubbles are greatly reduced.
