Taipei is full of extremely friendly and polite people. Pull out a map and there is a good chance someone will approach you with help. The place is very clean and safe and has a great food scene.
Insider Tip:- Use the Subway MRT to get around. It's cheap, very clean and very safe. - If you love food, do check out the street food options at the various night markets (but avoid Shilin which is touristy and doesn't have great food. Go to Raohe Street night market instead which is near the Songshan MRT Station) - If you really really love food, go on a food tour like Taipei Eats which is fantastic! - Go to the original Din Tai Fung restaurant. If you get there by 11.30 you won't have to wait too long.
