Located at Duxton Hill, MavRx (stylised with a capital R) is a small hole-in-the-wall joint that serves nothing but coffee. This minimalist, VERY Instagram-worthy shop boasts monochromatic decor and wooden benches for seats. When available, always go for the Chocolate Coffee Cone ($8) — essentially a piccolo latte in a sturdy waffle cone that you can nom on once you're done with your coffee. The chocolate coffee cone comes in three flavours — white, milk and dark chocolate. Otherwise, order the super fun Cold Brew ($5). Served in a large syringe that you can "inject" into your cup of ice, it's great for a mid-day caffeine boost or a pitstop after dining nearby!
