Don't know about the wine bottle opener. All of the plates/bowls are paper. There are 2 ceramic coffee mugs and 4 glasses. I'm under the impression that if you want 2 more mugs you can get them.
There are microwaveable serving size bowls ... if that's how you make your dip. Utensils for cooking are basic spoon, fork-type thing. For your eating, consider picking up a camping kit of portable plates and bowls...if you're going to do studios regularly. By day 3 the bowls get difficult to wash/clean. There is a very basic cork screw available. Have a great time...nothing is better than sitting on the patio with a glass of wine just watching the world go by.
Thanks-I wish I was there now-
I should get some disposable bowls for cereal and fruit type of items
I also need my ziplock bag so I will pack those-
what about a sponge -for cleaning-or dish soap?
