There are many restaurants in Manado. But I recommended you to try this 3 restaurant:
This restaurant provide all typical food in Manado. The special food in this restaurant is "Manado Porridge" or also called "Tinutuan". This restaurant also provide lake fish (Nike), Jackfish noodle (Mie Cakalang), fried banana, boiled corn, and other else.
2. Bambu Den
This restaurant provide 2 special fish in Manado. Goldfish (Ikan mas) and Tilapia fish (Ikan mujair). I like the spicy sauce in this restaurant. You must try the special water spinach too.
3. City Extra
This restaurant was built nearby the sea. This restaurant speciality is seafood. Don't forget to try the Red bean ice (Es Brenebon) too.
You'll never regret if you visit that 3 restaurant :) almost 8 years ago
