Thanks very much for the kind welcome(s)!
Yes the Town Wharf ought to be very busy in summer, especially since the Thames Path National Trail actually goes through the patio!
I'm a confirmed cask drinker so I tend to avoid the keg only pubs - although I do like the wheat beer and the stout, so if I absolutely have to go to a keg pub, Sams would be my choice.
Therefore, I haven't been to the Rose of York for years, and I wasn't impressed last time I went. Large, empty and unloved was my impression.
I did go to the Gazebo in September, as it was the only riverside pub in Kingston where I could get a seat - and as I'd just cycled 15miles I wasn't prepared to stand up and drink.
Again, considering its location I think it is probably underperforming.
