The Royal Blenheim menu attempts to designate vegetarian with a blue 'v' and vegan with a pink 'v'. Unfortunately in some cases the blue is green and in most cases the pink is yellow and in one case faded grey, probably a printer problem, resulting in a very confusing menu.
As a vegan I fell foul of this: when my partner pointed out that the nachos have both a blue and a second, faded, 'v' by them I opted for these with the veggie chilli. It arrived smothered in cheese which isn't mentioned in the menu description and isn't vegan. We had both read the menu as indicating that the veggie chilli option was vegan. When I pointed this out the barman told me I should know nachos came with cheese - funny that because they are offered elsewhere on the menu as vegan. He told me a blue v was vegetarian and when I pointed to the second v that wasn't blue didn't even attempt to explain it. He was very apologetic and polite but the attitude was one of 'the customer has got it wrong'.
The message came back that I was expected to pay again for a cheese free version which I wasn't willing to do so I made do with my chips and onion rings sides and spent a good part of the evening reassuring my partner that it wasn't all her fault. I didn't take up the offer to talk to the manager as I was feeling a little angry by now and was on my second beer so thought I'd just let it go. I did grab a copy of the menu so I could have a good look in the sober light of day and it is no clearer, in fact the array of different coloured 'v's is laughable.
To be fair I expect in different circumstances an enjoyable vegan meal can be had here but I doubt I'll be going back any time soon!
Cons: Menu needs clarifying
