Lorraine Watson has already battered the opposition in the world of deep-fried Mars bars.
And now, as she prepares to launch her second fish bar in Stonehaven, she is moving from chips to microchips.
Lorraine's Carron Bar outlet has become one of the town's most high-profile shops and has recently been visited by the likes of comedian Alan Carr and Aberdeen manager Derek McInnes.
But she isn't resting on her laurels and told STV about her plans to open a new chipper - The Redcloak - at the start of October.
This will feature an online delivery service and an order-and-collect facility for hungry customers.
She will start refurbishing the premises in Redcloak Drive at the beginning of September.
Lorraine said: "We've been thinking about a second venture for a while now.
"But we want it to be a bit different and we are working on setting up the online delivery operation.
"We don't just want to leap into it, because we have to make sure we can deliver top-quality food to our customers.
"And no, we don't plan to include deep-fried Mars bars, because they are so closely linked with The Carron.
"We are getting the range delivered from Holland in the next few weeks and my son, Murray, will manage the new shop.
"So it is going to be a very busy period between now and the launch."
When the Redcloak opens its doors - provisionally on October 2 - Lorraine is planning online deliveries for registered customers over a five-mile radius.
And details of the menu will become available at their website throughout September.
But Lorraine gave us a couple of hints.
She said: "We are trying to do lunchtime specials and these won't just involve fish and chips, but items such as mince and macaroni.
"We've also been asked about gluten-free meals, and I do sympathise with people who want gluten-free food. But it is difficult for us."
That hasn't stopped Lorraine in the past.
