Went here for a friend's birthday dinner. Situated in the heart of Main St. Unionville and probably the best pub/patio there.
The food was surprisingly better than I expected of pub food. Ordered the New York Steak that comes with Sauteed mushooms, garlic toast and a choice of a side ($18.99) and it was quite decent.
Service was quite slow, even when that patio wasn't packed. But at the same time, when you're enjoying the weather and a couple of drinks, it didn't bother at me.
It gets quite packed on most nights, so make reservations.
Definitely my go-to bar place in Markham now.
