Coffee Lovers is a little cafe in the middle of New Regent St, next to Stir. I stopped in on the way to work recently, and had a takeaway cappuccino. CL didn't look all that popular compared to the neighbouring cafes, so I didn't have very high expectations - but was pleasantly surprised: the coffee was excellent! Good foam, and the coffee beneath was deep and rich.
Note: This cafe is where Bagel Heaven used to be (25 New Regent St).
