This place has a lot of things going for it that make it a solid venue - plenty of space, easy to get to using public transit, & helpful yet not hovering staff who don't mind if you loiter all evening long just as long as you're buying.
Food and drinks are average price and quality, but do the trick. There's nothing groundbreaking or "must-have" about Scallywags, but it's a comfy and welcoming environment (doesn't seem as dank as other nearby pubs) and it's especially great for groups.
I can't speak for the times when it might be bustling with sports fans (there's quite a few screens about to watch games of various persuasions), but on a general week-night it's a great option for getting together.
