Honestly I think that the majority of the reviews people have written here are for the next door neighbor, Nagayama Cafe. Having lived half a block away for two years and indulged in both, hopefully I can clear things up.
There are three Naga(yama) restaurants owned by the same group right next to each other across from the Shell station on Bandeira in Itaim. While all three restaurants offer high quality sushi, they cater to different audiences with different menus at different price points. Located in between Nagayama Cafe and the upscale Naga, Nagayama is the more family oriented of the three restaurants with a stereotypical Japanese decor and broader menu of Japanese food.
Come here with your friends who have kids and sit in the back at the table which is up a tiny set of stairs so you can see over the bustling little restaurant. Try the tempura for starters and continue on to teriyaki if you can't stomach raw fish or for a healthier touch delight your tastebuds with a classic sashimi plate.
Personally this is my least favorite of the three restaurants, but they were extremely accommodating when we came with out of town friends who had their baby with them. It's still generally on point for fish quality but not as exciting as the other two. All three restaurants are expensive though perhaps at this one you can get full spending slightly less. read more
