Kings street is good for craft beer, The old duke at the far end is good for regular beer and the Apple is close by for cider.
The Three Tuns is great for beer and food but small ish, probably not going to be rammed early evening though.
The Grain Barge on the harbour is also decent, nice roof area if the weather is good too.
Wild Beer on the other side of the harbour is good for craft beer too, you’ll probably need a beard.
Slightly out of the centre, the tobacco factory on North St. has loads of room and a good supply of beer from the Bristol Beer factory over the road. The Hare, the Steam Crane and Wild Beer down the road are good stops on the way back into town too.
