Great find and awesom location!

We came here on a day trip to Osaka and loved it! It's so great that you can sit outside on the terrace with a view over the river. The food was super tasty, perfectly sized serving and not expensive, too. The Café looked lovely, the staff was really kind, we recomend the Optomus Cafe and will definitely come again! ☀️🌱

Pros: All vegan, Tasty food (also dessert) , Great view!

Beautiful view and nice food

The view over the river is lovely. The food is also great but was a little disappointed that the prices jump up almost 50% on the weekends… I get it but I’m also not a fan of such pricing.

All the portions are a little on the small side for me but only just. The summer bowl and Optimus bowl were excellent but I found the fried soy bowl a little disappointing.

I returned today for the hiked up prices and had the fried soy bowl. The soy “meat” was really spongy and greasy and there wasn’t enough freshness in the rest of the bowl to counteract it.

Other than the fried soy bowl though I’d definitely recommend this place for a light lunch.

Pros: Vegan, Affordable, Beautiful view

Tasty with great view

The soy chicken was awesome. Just like the view over the river. 1200¥ per lunch was very reasonable and well worth the money.

Absolutely delicious breakfast

Sat outside on the river. Ordering system was via QR code which was ok but the English translation wasn’t working too well. I ordered the big breakfast and it was the best ever! Tasty, fresh, thoughtful food. The kind of food you feel really good eating. I also had a smoothie that was fab. Friendly, efficient service. I noticed that there were around 6 breakfast options but that the big breakfast seemed to have sold out by 11.

Pros: Lovely space , Freshly made food with tasty ingredients , Great service

Cons: A bit pricier than other places but worth it

Okay food, great view

It's super nice to sit outside by the lake. Some breakfast foods were already sold out. The food we had was okay but nothing special. The avocado was a bit bitter and already darkened and also lacked in seasoning. The granola yogurt was quite good but the berries on it were still frozen which didn't taste great. French toast was very tasty. Great for the view and food is okay 👍.

Great breakfast spot by the river

It's not easy finding a breakfast spot in Osaka since most restaurants don't open until 11am, so I wasn't sure what to expect, but this place was great! It offers a peaceful and quiet atmosphere, and the location by the river is a great way to enjoy breakfast.

It's the perfect place to enjoy a cup of coffee and some breakfast while taking in the beautiful scenery. The staff is incredibly friendly and welcoming, making the experience even more enjoyable. The peaceful and relaxing atmosphere, coupled with the delicious food and friendly staff, make it a must-visit for anyone in the area.

Great food. I went for a late lunch and breakfast the next day. Both were fantastic. The Buddha Bowl and the English breakfast were both good choices for me.

Great vegan food; beautiful riverside view

Came in for breakfast around 9:30 AM on a weekday. The place was fairly empty. There were blankets for those sitting at the patio (since it was quite chilly outside and also some of the seats are made of metal). Breakfast menu consisted of various toasts and a small breakfast plate

Pros: Fully vegan, Patio overlooking the river

My kind of place

Completely plant-based and mellow lunch café with the most delicious and healthy rice bowls, wraps, smoothies and sweets. The soy meat might be some of the best I’ve had. The first page in the menu had a list of recommended documentaries to educate yourself on veganism and environmental issues, which I think is a great idea. Nice view on the Tosahori river too. Optimus Café is my kind of place.
