Gervonta "Tank" Davis got a dope surprise for his 27th birthday -- a luxury dinner party with fam and friends ... including the Queen Bee herself!
Lil' Kim pulled up to the champ's birthday bash on Sunday ... a surprise put on by Tank's brother, Meech.
The shindig went down at Mau in midtown Miami and was only for Tank's close circle -- including his newborn baby -- and it looked super lit!
You can see the tons of balloons in the fancy dinner setting .
