Spending December in Dubai and decided to do the same I did in Cyprus for the past month and a half - self-catering. Of course it’s not the best solution for a family coming on vacation that doesn’t want to bother with cooking. Other than grape juice and milk (you can bring 5 bottles of wine in and they also sell here) there is everything you might need in stores like Carrefour Hypermarket. There is a small selection of items carrying OU and such, but what comes very handy is to have the European kosher lists that explain items and details such as factory codes (I rely on Paris and Zurich) as many items are manufactured there. There is kosher chicken available as well. I really don’t feel like I’m missing anything. I’m not sure if cholov Stam milk is available, perhaps some UHT is, but other cholov stam items are readily available as well.
