I lived round the corner from Red Box during my first year of uni and found it was a lovely place to have brunch with flatmates or study while having something to eat/drink. Loads of GF options (and VG as well) and everything is very clearly listed on the menu. I once had to double check the bread was GF because it was so good! Desserts are also offered and the coffee is great.
