The best way to describe Matt's is "breakfast nirvana." I've been going to this cheery downtown spot for weekend breakfasts and weekday lunches for around 2 years now and have never been disappointed with the food. Small touches of quality abound: freshly-ground pork sausage patties, perfectly browned, homestyle potatoes o'brien (not of that cubed pre-frozen crap), thick-cut bread with homemade jam, and what tastes like real maple syrup for Matt's awesome pancakes.
What keeps a breakfast enthusiast like me from hitting Matt's at each opportunity are the insane queues, especially on weekends. The air conditioning can also be a bit sketchy at times, too, given the cramped space and swarm of humanity in there at busy times.
