Riverside Terrace Overlooking Temmabashi and Okawa Turns into a Gyoza Bar! "Gyoza Stand & Sour Garden" Opens on June 8 (Mon) with Incredibly Cheap All-You-Can-Eat Gyoza, Karaage, and All-You-Can-Drink Sours

A large-scale beer terrace project lasting about five months, utilizing one of the few riverside terraces in central Osaka.

Temmabashi River Cafe, operated by Operation Factory Co., Ltd., will hold the limited-time "Gyoza Stand & Sour Garden" event from Monday, June 8, 2026, to Friday, October 30, 2026.

On the open riverside terrace overlooking the Okawa River, guests can enjoy all-you-can-eat menus including freshly grilled juicy gyoza, sinful cheese potato fries & karaage mountain, plus all-you-can-drink from 50 types of beverages for 2,990 yen per person (tax incl. 3,289 yen).

Furthermore, we offer a premium all-you-can-drink option featuring "Frozen Mug Draft Beer," where the mug itself is frozen before serving.

Located in central Osaka yet offering a waterside open-air feel, this limited-time event is perfect for gatherings with friends, an after-work drink, or toasting from summer through autumn.

"Osaka summer is with sours by the river."

Not as expensive as a beer garden, more open than an izakaya.

Temmabashi River Cafe proposes a new tavern experience by the river.

Enjoy the night view of the Okawa and the river breeze while savoring freshly grilled gyoza and toasting with ice-cold sours or highballs.

We offer a special time from summer to autumn that can only be experienced at one of the few riverside terraces in central Osaka.
