I blogged about it 2 months ago, and now it's open. Mackenzies opened for business last Thursday afternoon and is open every day from 8-8, including Fridays. The store is located in MQ, in the same building as Costa Coffee, just next to the Busy Bees nursery (behind Subway).
The place is split into 2: a Cafe at the front with lots of comfortable seating, and then at the back is the deli selling freshly imported products ranging from salmon & mussels, to fresh beef, lamb and pork products. The cafe has sandwiches which change every few days, and there is even freshly baked bread flown in from, I think the lady said, Belgium.
Freshly made pies, ready for you to take home and bake in your oven, are also available, along with an extensive fresh olive selection and more. It's certainly worth a look in, I was quite pleased to get a jar of lemon curd (not seen that for sale here before)!
