Sailloft is fairly new, has a good range of beers and is by the river -
The Sail Loft - Fuller's Pub and Restaurant London
Oystercatcher - more Bar/restaurant, pretty much next to the Sailloft -
Oystercatcher Greenwich
Cutty Sark - further along the river to the east, past the power station but still easy walking distance. Great on a sunny day.
Cutty Sark
The Trafalgar - bit more touristy, being right next to the college, but has outdoor seating and reasonable beers.
A bit further inland, there's the Plume of Feathers, just by the park -
The Plume of Feathers, Greenwich London
The Mitre (
The Mitre in Greenwich), Greenwich Union (
The Greenwich Union) and Richard 1st (
Richard The First) have all been good when we've visited.
There's also the Meantime Brewery a bit further along which has a bar etc.
The Old Brewery in the Old Naval College is nice when there's no one else there, but not so much during tourist season...
Gypsy Moth is okay, tends to be busy, but easy to find, being right next to the Cutty Sark ship.
