The images look delicious (if something can "look" delicious). However, I do have a couple of comments...
1. Your images appear to be generally overexposed. IMO, bracketing exposure is one way to nail down the absolute best exposure. Some photographers look down their noses at exposure bracketing but, it is certainly a valid tool. Additionally, when you have shot using a tripod and adjusting the exposure with the shutter speed, it can sometimes be beneficial to do an HDR image...
2. The soyu botle in the upper right of #1 is distracting to me. I would like to see either more of it in view or eliminate it altogether...
3. I would suggest using a tripod (I suspect from your ISO and shutter speeds that you did not). Using a tripod will enable you to shoot at a smaller aperture, such as f/11, for a wider DOF and a lower ISO, such as 100, for better image quality. You can easily manage your exposure using the shutter speed since the images are non-moving...
4. I would also suggest selecting a table cloth of a slightly different color so that there would be more definiton between the edges of the plate and the table. Possibly, a choice of a different color plate might be a better choice than a different color table cloth. A small collection of serving dishes, plates, napkins, table mats, etc. of different designs and in different colors can be a great tool in setting up food for photography.
BTW: as a reply to Tonyjr's comment, "BUT remember that macro lenses are for close focusing and have very small DOF ." Macro lenses are certainly not needed in a case like this. I agree that when shooting at the close distances often required when doing macro work that the DOF can be razor thin. However, there is absolutely no difference between the DOF of a normal and a macro lens of the same focal lengths when they are shot at the same distance, same f/stop and same point of focus.
