I might be seeing spud shack's rosti reviews onlime b4 but its probably out of my way to try their rosti in the past. Both rosti flavour we have ordered is their best selling.
My sister ordered Garlic Pepper Rosti ($7) w Chicken Spicy Sausage ($3.50) and she told me that it's not bad but I felt that their chicken spicy sausage was mild spicy taste.
Whereas I ordered Torched Mentaiko Rosti ($8.50) w Chicken Chipolata ($3.50) but the sauce was quite creamy, milky and a bit heavy and thick texture. Their rosti was quite crunchy and crispy on their outer skin. Got a bit harden on some certain part for potato. Chicken Chipolate was mixed herb based filling and got that unique aromatic taste.
