There's been a Starbucks built into Sainsburys for some time, however during the holidays a Caffe Nero has been started in the town (a really nice one, good building, layout e.t.c.) where my school is (Tonbridge). There is a certain amount of debate as to which is better.
I rarely go to either, just don't like the idea of spending money!
I'm not saying these are the best you get, their aim is to make consistent tasting coffee rather than the best. However out of these which do you prefer allowing for staff, efficiency and most importantly the coffee/other beverages
