OK – last one of the day!
For budget purposes, I think you should allow a minimum of US$30 per day for food. This dollar value is based on doing a couple of simple things like buying a loaf of bread or cereal for breakfasts at the homes you’re all staying in rather than eating out for brunch every day, and maybe doing a quick supermarket run for having snacks in the car rather than buying lunches and nibbles at more expensive rest-stops.
There are a few days where there will be an opportunity for eating at some very fine restaurants if you so desire: Monday 4th January out at MONA for lunch is one of these days (although they have a full range of options including BYO and eating picnic-style on the lawns, plus a cafe if you’re not wanting to splurge in the award winning restaurant). Monday 4th Jan in the evening is another: I’ll most likely be down at the Salamanca Waterfront where there are many great places to dine. Thursday lunch at Frogmore Creek Vineyard could be had for less than $40 if you only wanted one course and wine; again, you could picnic in the park if that suits your budget better. Friday lunch at the Jetty Cafe at Dennes Point on Bruny Island will probably be about $30-$40 per person if you want a wine or beer with lunch then coffee with dessert; Thursday night I’ll most likely be in the North Hobart area where there is a fantastic, bustling restaurant strip (say $30-$40 for this too). And don’t forget you’ve already paid for dinner on the 2nd and 3rd of January 🙂

Monday is the 5th
Thanks G&P… losing track of the dates 🙂
