Mojo always does great coffee "to-go". I feel like the set up of the cafe (being in the middle of an arcade) isn't the easiest for sitting down and enjoying a hot drink as there's people pushing past all the time. However can't fault the coffee.
Great location especially when in summer when you can sit down have coffee and see the centre of Wellington working.
It is also a great place for on the go coffee, where the coffee being made is amazing.
