Yuna
155, 18-19 Sukhumvit 11/1 Alley, Khlong Toei Nuea, Watthana, Bangkok 10110
Sit at the sushi counter. Yuna runs as a working izakaya with a sushi bar at the heart of it, and the Toyosu sourcing is the reason to come at the counter rather than a table. Call ahead for a counter seat at dinner. Lunch takes walk-ins without reservations, which is how to discover the room before committing to a full evening.
Soi 11/1 is the address. You turn off Sukhumvit 11 onto the smaller branch soi, and Yuna sits in a calm room with the sushi counter as the spine, three minutes on foot from BTS Nana.
The seafood is the lead. Yuna sources directly from Toyosu Market in Tokyo, and the menu builds out from that supply line into sashimi, sushi, charcoal-grilled wagyu sets, scallops, yakitori, tempura, tonkatsu curry, and Japanese set meals. The room sits inside the Sukhumvit 11 cluster but at one remove from the strip, which keeps the volume lower than the bigger Soi 11 venues a block away.
The operating rhythm is split. Lunch service runs 11:30 to 14:30 and does not take reservations, so the midday window works for a walk-in solo seat or a small group without planning. Dinner runs 17:30 to 22:30, and the counter seats fill faster than the tables. Call ahead if you want the sushi bar at dinner, especially Friday and Saturday.
The interior holds a traditional Japanese register. Wood, a calm light level, and the chef line visible from the counter seats.
Nana BTS is the entry point. Walk south down Sukhumvit 11, take the right onto 11/1, and Yuna is a short way in on the right at numbers 155/18 to 19. Skytrain access means a clean route home after a longer dinner with sake.
