We just arrived in MR last night and are looking forward to exploring!
In Melbourne, we enjoyed meals at Dainty Szechuan, Laksa King (both favorites of the friend we are traveling with) and Matilda. On Phillip Island we had lunch at the brew pub next to the mini golf place (can't remember the name, but it was good) and dinner at Pino's Trattoria (also pretty good, and seemingly the most popular restaurant we passed). The penguins were awesome to see and I recommend paying extra for the VIP seats.
In Broome, we had lunch at the Dragonfly Cafe downtown (good fish tacos) before doing a 30 minute camel ride and then driving down to the Ramada Eco Beach lodge. The resort was very remote, and once you are there you are pretty much stuck. It's nice if you want a few days of doing nothing, but not worth flying across the world to IMO, but the locals love it.
