GA is the only fully vegetarian pub/restaurant in Oxford, and it caters well to vegans with around half of the (small, unchanging) menu being vegan. I've been here a few times now and while it's nice, it's never quite good enough to justify the price (as another review mentioned, you're looking at £8 for a burger with a bit of tomato/lettuce and a basket of chips). I wouldn't mind paying extra for the benefit of eating at a fully veggie place if they didn't fall short in so many other areas eg they stop serving at 7:30pm (and this is a completely food-centric pub, remember), the food doesn't taste that great and never changes, etc. Lots of people love this pub but personally, I was disappointed.
I've since realised that it's only on Sundays that they stop serving at 7:30pm, most days they stop at 9, which is much more reasonable. Also, I've since been back with other people and they both commented on how cheap and delicious the food was! I guess it's a matter of perspective haha :-)
Cons: Feels Like They Charge Xtra
