Realistically how much time have you got with each dish?
Proper styling in the middle of a pub probably isn't going to happen.
Quickest way is soft flash lighting to the rear of the food and use reflectors at the front, just make sure you have consistency between each shot as I guess they are going to used on the same web page/menu?
I used a mixture of 24-70 or 90 TSE lenses for the foods books I've done, make sure you don't blow any highlights and the food looks clean and bright.
