Apart from pretzels, Pretzel Perth's 'thing' is pink. I am not sure about the Northbridge store because I have never been there but the Carousel store is 99% pink. Whilst this may sound unappealing for some it actually gives the store a very hip and trendy vibe and I loved it.
The pretzel menu is small but impressive. They offer a selection of savoury and sweet pretzels, all of which look delicious. I had the salted caramel pretzel and tried some of the cinnamon one. Both of which were great. The dough is perfect - it's not too soft or too hard and the flavours were awesome.
I also thought the prices were very reasonable. It was $5.50 for the cinnamon pretzel and $7.50 for the salted caramel and the most expensive pretzel on the menu was $8.50, which I consider exceptionally decent given their size and quality.
Warm drinks are also on the menu, making a pretzel the perfect companion for your mid-day coffee.
