Found Dingo Deli today for lunch and later for a coffee. We will definitely be back, the food is very good, for western food in Vietnam I doubt you can do much better. Coffee is good here if you need a break from the Vietnamese beans.
Staff are ok, it would be nice if they smiled a bit more. But the Australian lady we believe to be the owner is friendly.
We noticed the jungle gym out back which looked great for kids. They also sell a large variety of western produce such as Heinz baked beans, cheeses, meats etc... great if you have sudden craving.
