On Battersea Rise near Clapham Junction lies the Walrus Room cocktail bar, which also offers small tapas dishes with a seafood specialty.
Cocktail list is pretty extensive and priced reasonably at £8 or £9. I recommend Through & Through (vodka, ginger, lime) and Something Naughty (Amaretto, Campari, triple sec and lemon). Lovely interior decor with a Victoria type setting. The cocktails are inspired by Lewis Carroll’s The Walrus and The Carpenter, each of them taking their name from a line in the poem.
Open until 12.30 on Fridays and Saturdays.
