Eat Around NDHU - Your Foodie Guide 

Taiwan offers a NT$5 discount for bringing a reusable bottle to convenience stores or cafes as part of its environmental policy. 

If you're a beginner or not very good at using chopsticks, it's a good idea to buy a set of reusable cutlery to keep in your bag.  After you finish your meal, you can wipe them down with a little water or a napkin, then wash them properly with dish soap when you get back to your place. It's a great way to be environmentally friendly!
