Costa; Any of there Frescatos, or Hot Chocolates or Herbal Teas awww I could kill for a Summer Berry Frescato they're delicious!!!
Starbucks; Been in once, was far to overpriced, staff were all miserable and it was full of middle aged women with babies, and teenagers trying to act cool....
I love Esquires especially their hot chocolate with honeycombs, whipped cream and chocolate sprinkles!!!
