Some tips:
1) Make reservations. The local shops close early so it's often a bummer to wait.
2) Half-price apps on Mondays (except Nachos)
3) If it's your first time, look up the location on Google Maps - can be a bit tricky to find if you've never been to the Distillery District
Mill Street's brew pub is a very decent establishment that's fairly consistently good when it comes to food. Mill St. beer is pretty good too.
It's pretty spacious inside and there's a place to buy Mill St. beer beside the entrance. The decor is pretty standard for pubs.
Food-wise, our group ordered Fish and Chips, Butter Chicken, Atlantic Salmon and Beer Brined Chicken. We were all pretty satisfied with our orders. Nothing stood out as exceptional but nothing was bad either.
The waiter was obviously very busy but considering how busy it was, we still received relatively good service, just slightly longer than expected waits.
