If you're wandering around Khalidiya area, looking for a new coffee place that is quaint and want a bit of peace, look for Mix Box Cafe.
Place is mint clean and cosy (tho artificial plants can be overwhemling. I just wish they used real ones). ☕ Coffee is good (in my opinion), strong and flavourful. Friendly staff who serve your coffee with their logo-engraved little wooden trays. Food, not too sure (not so happy with my cake).
The bonuses: they close late... (I think) they're serve until 1am. Plus, they have a WC!
