I was very unhappy when Pionic on Campbell closed - i missed the "build your own" with gluten-free options.
I liked the atmosphere at Pionic slightly better - more wood and slightly more similar to a pub feel, but MOD is clean and airy with a good vibe.
The staff are all extra friendly and helpful.
The pizzas are good. My main suggestion would be to make them a little less dry by extending the sauce all the way to the edge of the crust - a personal preference, but it goes a long way toward keeping the thin crust from getting too crisp in the oven.
I like the variety of toppings and sauces and they have a lot of really good salads.
