Living not far from the Bush as I do, I know there's a Wetherspoons in the shopping centre, opposite the tube station. From there I would say about a 15 minute walk to the ground... JD Wetherspoon; The Central Bar Shepherds Bush
There's also O'Neills and Walkabout that let away fans in apparently. I think I'm going to Byron's in the Westfield Centre for a gourmet burger and a couple of bottles of plonk.
I've been in both the Walkabout and O'Neills on match day and never had any bother. Some good banter in both as well. Preferred O'Neills as a preference. Not been in the Wetherspoons in West12 shopping centre. The only time I'll be going in the Westfield this week is suitcase shopping. I was looking forward to the QPR game and forgot I'm off to NY on Monday
