Nana Seafood at 231 Sukhumvit Road is a casual branch serving seafood and familiar Thai dishes in a very convenient central location. The menu is broad and the long opening hours make it useful when many conventional restaurants have closed. This is a straightforward tourist-area restaurant rather than a specialist fine-dining seafood destination.
The exact Soi 17 branch shows a mixed Google rating around 3.5 out of 5. Positive comments focus on convenience, fresh seafood displays and dishes such as crab fried rice, morning glory and oyster omelette. Critical reviews question consistency, pricing and the overall value compared with other Bangkok seafood restaurants. It can work when location and hours matter most, but check prices carefully before ordering larger seafood items.
