We went to Perseverance for dinner because we wanted to go somewhere within very easy walking distance of the Cockpit Theatre and that, for some reason, is located in a weird no restaurant land. A mile to the north, many lovely Lebanese places, a mile to the south, the posh places of Marylebone, but directly around the Cockpit Theatre, nothing at all. Who knows?
Anyway. Having not very graciously at all decided to go there on grounds that it seemed to be the only place that was remotely close enough to the theatre to make sensible, it was actually very nice. For some reason, looking at reviews, Timeout seem to be the only people who dislike the place, as everyone else notes, it has an inventive menu that is well executed. The atmosphere was nice, fairly quiet, good service, though I always find it weird to have table service for drinks in a pub. Vegetarian options were fairly minimal - just the one main course option but as it was a very nicely done risotto, I was pretty ok with that. I particularly liked that the apertif on the menu (an elderflower bellini) was actually priced quite reasonably (£4) for London and so I didn't feel like a total spendthrift for having it.
