Go for it and have a good time. I take food pictures ALL the time whilst on vacation. I even have a fantastic picture of my mom's dessert when we were on a cruise in Alaska 7 years ago. I always think that plate presentation tells a great story. Have fun. The only request I ever had was from my daughter when we were in London asking that I NOT take a picture of her minestrone soup because she was afraid it would come out looking like barf in a bowl, so I respected her wish!!
