The service was a little patchy - either very prompt or very slow depending on the staff member, but I was willing to cut them some slack, given how busy it was.
The interior is rather British, without having to rely on pictures of the Queen everywhere. The bar is small with a low roof and a forest of "imported" beers on tap.
I use the quotation marks because, despite the claims on the menu and website, the Guinness doesn't come from Ireland and the Bulmers doesn't come from England, but those are fairly small quibbles, as the Old Speckled Hen and Abbot Ale are definitely from England.
Despite the name, the bar is basically British. It is utterly unlike any Irish bar I've been into, although that isn't a criticism. I am merely bemused as to why it's called British Isles when the only remotely Irish thing in there is the New Zealand-brewed Guinness.
The wine list is pretty good and the spirit selection is more than adequate as well, so it was all looking fine, really.
Then we ordered the food, which was certainly British - chips with everything. There is always a danger when places offer "traditional British food" that it will taste exactly like traditional British pub food - stodgy, fatty and oddly tasteless. What we got certainly wasn't tasteless, but it wasn't exactly great either. It certainly wasn't to the standard you come to expect from the average Kiwi hostelry.
Still, I wasn't there to eat, I was there to see what it was like as a pub and I have to say it really did remind me of pubs back in the UK. I just wish they hadn't mixed up British Isles with simply British.
