Chill healthy eating outdoors. Great place to grab a brunch before walking around town. Super relaxing and cool hang out for day drinking. On crossroads of main streets, so it's a great place to people watch.
If you are in Melbourne for a few days and looking for a few-hour excursion outside the city, St. Kilda is a neat suburban town on the water to visit. Very easy to get to via train from Melbourne. Cute little town to visit outside the city.
