Mocha Cafe is on the busy Charing Cross Road not far from Trafalgar Square and Chinatown but it feels hidden away because it's part of a row of shops that's set back from the road, under an office block that overhangs it. This is a nice, clean-looking, bright cafe that also has internet access.
Ordered my sausage sandwich toasted on brown bread, with brown sauce. It was only £1.70 which is cheaper than average. Not much to look at but the sausage was of higher than average quality. On closer inspection, I found the sausage actually contained herbs! Not something you see in your typical cafe sausage sandwich. The brown sauce used was good - not diluted rubbish - and overall it was a nicely made, inexpensive sausage sandwich.
3 out of 5. Best so far.
