Open menuWhy it's worth checking out
Sonny Boy Vietnamese Kitchen is a locally owned restaurant in Subiaco, Perth, offering a mixed-Asian buffet-style dining format rather than a fixed menu. Diners choose what they want for their bowl, then pay by weight, making the meal flexible for different appetites and preferences.
The venue’s central idea is participation: you assemble your own bowl from the available selection, giving you control over the combination and portion. The website describes the food as offering a range of options and places an emphasis on good-quality ingredients, although it does not list individual dishes online.
Located at 1/50 Subiaco Square Road, Sonny Boy is presented as a comfortable place to eat, with a broad selection available in one setting. It may suit diners who enjoy choosing their own meal and want the freedom to try as much or as little as they like. The restaurant is run by an experienced local family, adding a personal connection to its Subiaco setting. For specific buffet choices or current service details, it is best to contact the venue directly.
