1) The servers take orders on a mobile phone app. It's probably the worst customer experience you can have because there is almost no interaction with them. Just them staring down with a florescent light coldly illuminating their face. I understand there may be some advantage with regards to restaurant operations/efficiency but Gusto 101 isn't a factory. You're going for the overall customer experience and I believe the mobile app they have employed with their servers significantly impacts the vibe they're trying to create. If management is insistent on the mobile app, install iPads at the tables, have the customer enter their own order and save their tip.
2) The bathrooms are shared. If you are dining on the top patio, you have to walk to the basement to a room with shared sink with 4 or so private toilets. The toilets themselves are private, but there is no Men's or Women's designation so it's a free-for-all. Men and ladies' private business should be kept private, not shared, especially at an mid- to upper-end Toronto restaurant. Surely they can modify the basement to accommodate for two separate facilities.
I would only go back if a group of friends had already planned to go there. I wouldn't recommend for dinner.
