The Taiwanese people are usually friendly, hospitable and laid back, so most regular restaurants do not have a dress code. Many western fast food outlets, cafes and restaurants such as McDonald's, KFC, Starbucks can be found in downtown Taipei and are open either from 7am (if breakfast is served) or 11am onwards all the way till as late as 9,30pm or 10pm. Casual Chinese shops and restaurants such as Din Tai Fung and franchised Japanese restaurants, unlike formal Chinese restaurants which are closed on weekday afternoons from 3pm through 6pm, remain open throughout the day. As long as one feels peckish, it is easy to find a decent and reasonably priced place to eat in Taipei even without holding any reservations. In fact, many popular casual restaurants do not take reservations, accepting customers on a first come, first served basis.

No visit to Taipei is complete without a visit to the specialty noodle and dumpling restaurants such as Din Tai Fung (with branches throughout the city) for atypical casual Chinese staples such as beef noodles, pork cutlet noodles, steamed soupy dumpings (xiao long tang bao).

Most department stores such as Hankyu and Pacific Sogo operate air conditioned self-service food courts where you get to enjoy dishes well loved by the Taiwanese such as oversized chicken cutlet (hao da jih pa), braised pork with rice (lu rou fan), noodles with a robust flavoured minced pork gravy (zha jiang mian), minced pork dumpings served either in a bowl of steaming broth (bian shi), or  tossed with chilli and soya sauce (hong you chao shou).

Except for the family or proprietor owned food outlets and shops which do not levy a service charge, most restaurants in Taipei that levy a 10% service charge, accept international credit cards such as Visa, Mastercard and JCB. Tipping is usually not expected at these restaurants.
