LOVE THEIR PATIO! This place has one of the nicest patios in Toronto. Who wouldn't want to enjoy a pint of their favourite beer under the canopy of the two majestic trees they have. The tables are well spaced out, the patio is enormous and they could easily pack another 5 or 6 tables back there, but they chose not too and this makes that space all the more comfortable and inviting. They have built-in seating surrounding the trees, so you can't help but feel like you're in someone's fabulous backyard.
Their beer list is extensive and their wine offerings are impressive as well.
Service was quick and our waitress was friendly.
One thing of note...we had visited another pub earlier in the evening and we're given a list of "don'ts" before our server would even take our order, due to "by law restrictions" and yet 4 doors down, those restrictions (no tables of more than 6 ppl, tables couldn't be moved) somehow magically disappeared at Allen's.
To be fair, I didn't try their food, but I'm basing this review on my beer drinking enjoyment and this place was near perfect. I'll update the review once I've tried their food.
