Restaurants around Flinders (Nut Allergy)

Hey, I got a group of friends going to Flinders Street and we are going to get food but one of us has a nut allergy so looking for some recommendations, doesn't have to be too expensive or fine dining but it is for a celebration. We were going to go to Supernormal but couldn't get a booking and seems a bit pricier than we would like, with that information does anyone have any recommendations? Ideally walking distance from Flinders Street thank you.
