My recommended route is in Gongbei, within walking distance, shopping and snacks.
I suggest you have tea first in the morning. Several seaside restaurants in Gongbei are good, such as Jinyuexuan, which is more expensive. Popular downtown, such as Guangdong sea.
Then you can walk along Lianhua Road Pedestrian Street to the underground square of Gongbei Port (there are some snacks along the road, such as peeing beef balls, kebabs, octopus balls and Turkish barbecue cakes, but you can only eat them casually. Those kebabs are too salty, but the squid skewers are still quite fragrant).
Further on, there is my favorite "Four Seas Fish Eggs", which really ranges from snacks to big ones. However, I suggest you eat it in the Port Square. Although it's the same boss, I always think that the curry in the underground square of the Port is thicker and more varied. Not just selling fish eggs, there are many, many varieties. Small fish eggs, soup dumplings, beef balls and curry sauce are recommended. The place is very crowded, so it is recommended to eat it packaged.
you'll have to go shopping in the port square, with clothes, shoes, socks and bags, which are dazzling. After you eat the "Four Seas Fish Eggs" (I forget which entrance, but everyone knows it), take a stroll and digest it. Go to the "food street" at the gateway, and follow the fragrance, you can buy the ice cream that I must eat. Durian, mango, taro taste is the first choice, and of course there are many other flavors. In the food street, many Hong Kong and Macao tea restaurants choose fast food "Cafe de coral". Or I must go to the "Hai Chun Qing" herbal tea shop, where you can eat many authentic desserts, such as walnut paste, papaya chinese forest frog, my favorite hot sesame paste and sugar, or have a cup of herbal tea to clear your stomach. Next to this, you can buy handwritten letters, that is, hand gifts. Many of them are so-called dried meat from Macao, and the taste is good, but you must see whether the plastic transparent bags they give you barbecue slices are printed in Zhuhai or Macao.
For lunch, you can also choose from many restaurants on the first floor downstairs. There is a noodle restaurant whose name I forgot. The bowl is bigger than the washbasin. It should be delicious if many Macao people come to eat it.
In the evening, if there are many people, you can go to the seafood street in Wan Chai to eat seafood. The advantage is that you can choose fresh seafood yourself, and then go to any restaurant nearby to process it and pay the processing fee. The disadvantage is that you have to be crowded to taste more flavors, and the price is definitely more expensive than eating in a restaurant, just to make it lively.
If you are few people, you should come out from the port square and walk to Gongbei Hotel. Their Cantonese cuisine is really good. We recommend wooden bucket chicken, as well as some seasonal seafood and stir-fry. After eating, you can also walk along the lovers' road and look at the night scene.
If you want to eat somewhere else in the evening, you can try "Pork Belly Chicken" on Yuehai Road, or eat hot pot with porridge at Longzhou Bay, or eat at the Japanese buffet in Metropark Restaurant of Star City Hotel in Jida.
