Brew Garden

Long after most central London cafés have shut up shop, this Bloomsbury/Holborn spot is still pouring — weekday hours run from 7am right through to 10:30pm from Tuesday to Thursday. The focus is Italian-style speciality coffee, roasted in small batches around a signature 100% Arabica blend, with outdoor seating for when the weather plays along. A 4.4 rating from more than 800 reviews suggests it's doing plenty right.
