A first type of nightlife: nightlife at seafront of Toamasina suburbs . People watch sunset, then prepare for campfire, with guitar serenade, harmonica and good friends around. Stay there till late at night. This is my fave.
In the past, it was possible to do that on Toamasina city seafront but not now anymore. Over there, you only have to watch people in Bd. Ratsimilaho and crowd passing by. Do not stay there too late.
Dress Code: No jacket required :-)
Indeed, no dress code
Please carefully read my Toamasina city page to know about my thought on this activity there (3rd part: "Nightlife, Nightlives")
Clubs are at: Neptune, Queens, Macumba...
Dress Code: Depends on where you go
