This place is arguably better than the other locations because of one reason: portion size.
Ritual, or walk in. The portions here are noticeably bigger than their other locations on Yonge (College, Gerrard) and they're not cheap on the protein either. The people here seem genuinely nicer too. They do have this strange rule written that seats are for dine in only but they've never kicked me out when ordering a Ritual and staying.
As for authenticity, I don't expect it for most ethnic chains. Ritz is no exception. They cater to Westernized palates (generally this means adding a ton of sugar). Going to Jamaica and having real BBQ and Jerk chicken/pork was eye opening.
If you're getting lunch, Ritual is a must.
