Great Place for Breakfast or Lunch

I came here several times for lunch or Breakfast. The place is often busy but you can get a place with a little waiting time or you kind of go to an off schedule time. I loved the food every time I went there! Staff manager (or owner?) speaks English very well. Ordering is via online Menu in English possible. The view of the outdoor deck is amazing! Definitely recommend!

Pros: Great view, Delicious Food all day, Free WiFi

Cons: Might have waiting line on popular days

Brilliant breakfast

A great restaurant right on the river in Osaka. The breakfast bowl and French toast were very very good!

Best by far

Lots of vegan options in Japan but haven’t found one that blew me away. This one did. Without my knowledge, I showed up 10 minutes before their kitchen closed and was super bummed as another restaurant turned me away and I was desperate. The man at the front cleaned off a chair for me outside with a water view and brought me what he could which was PLENTY and a complimentary tea. The unconditional kindness meant everything. And the food was the best I’ve had in Japan so far.

Delicious vegan food by the riverfront

Very nice location by the river in downtown Osaka. There's even an outdoor patio overlooking the river, however there was a long line for patio seating. Service was quick and efficient despite the busy lunchtime rush. The food served is a sort of healthy-ish, Japanese fusion cuisine. It was great as I had been craving some salad and veggies. The karaage bowl was delicious!

Good breakfast

Service was quick and friendly. The "big breakfast" was good, a bit cool to my liking when served. The French toast was the highlight - quite delicious and would have ordered that again. It was also nice to order matcha lattes with soy.

no

the bowls were ok, prices high and too 'healthy' (a lot of salad) for me, so you are not very full after. we tried going some other day at opening time and were told they were suddenly closed because of too many people, it looked empty and reservation was not easy to make so i doubt they all had it

Breakfast with river view

This cafe was close enough to our hotel and opens early to have breakfast. We tried granola with soy yogurt and a breakfast of toast with hummus and a soy meat patty, cappuccino and hot chocolate were among the drinks. Granola is delicious, breakfast is probably a bit simple for those who are used to eating something more interesting for breakfast. The drinks are good. There were many foreigners and Japanese, the terrace was fully occupied. The place is cozy and credit cards are accepted.

Good food and very nice terrace

The food is good but not amazing, prices are a bit on the high side and the terrace is great.

Ate here twice

Really tasty food and great option for lunch. A little pricey but most vegan places are in Japan. I enjoyed the Optimus Bowl. We also had the Keema Bowl. You order on your phone. You can ask for inside or outside dining. Outside they provide blankets and there’s a lovely river view.

Amazing fried soy meat and healthy Buddha bowls

I had the fried soy meat plate and orange ginger soda. I finished off with the matcha brownie, served warm.

It was all so delicious that I've been back a second time. This time having the seasonal Buddha bowl and a side of the fried soy meat.

Definitely worth a visit if you're close by.
It can be busy at lunch time so you may need to queue.

Pros: Great quality, Lovely staff, Good prices

Get the French toast

I was so excited to see somewhere that opened early. I had the French toast and an oat milk coffee and my partner had the breakfast plate. The French toast was amazing. The cinnamon was the perfect amount added and I enjoyed the whipped cream. My oat milk coffee was a bit sweet for me. I don’t add sugar so I don’t know if the oat was sweet or if they add a sweetener. My partner didn’t think the vegan breakfast plate was amazing, but I’m rating it based on the French toast with 1 point off for the coffee.

Good food

Ordered the Optimus salad, which was really tasty and would recommend.
Husband ordered the wrap, which he didn’t rate too much. Lemonade was also a bit weird (hence the minus 1 star).
For me the price was very responsible. 21€ for two main meals, fries and two drinks…

Great view over the river😄

Pros: Great view , Good salads

Nice

I went to Optimus Cafe today for lunch with my best friend and it was nice, she tried the Optimus bowl and the soy fried meat and I had a soy meat peta with truffle fries and a tiramisu for dessert.
Everything was good except for the smoothie my friend had for dessert the Be Beautiful because she didn't like the taste of beet in it but that's her preference more than the quality of the beverage.

Pros: Great plant based meats , Cosy

Cons: Far from a lot of things

Vegan bowls

They offer mainly vegan bowls. We got the Optimus bowl and the soy meat bowl and they were pretty similar besides the protein parts. The Optimus bowl came with an interesting corn fritter which was new to me. Healthy bowls.

There are few tables on the terrace available; offers a nice river view.
Inside are more tables with air conditioning.

You see the menu and order via QR-code. It didn’t take long for our food to arrive. But later we ordered another drink and that took quite a while for being just a drink.

Pros: Outdoor seating with river view

Genius

A beautiful cafe in such a pretty part of Osaka, sit inside in the cool AC or risk the heat outside for beautiful views of the river.
We stayed across the road at the onsen so we went here a couple times and the biggest highlight which we didn’t get a pic of was the French toast. This place is worth 5 stars alone just for that. It was unreal, like it was actual egg fried French toast with cream and maple syrup. If you’re missing French toast since going vegan, you gotta try this spot.

Pros: French toast , Have a good day breakfast set , Location

Fried soy meat goodness!

So many great options to pick from! Friendly staff with badges to indicate English speaking staff. Nice view overlooking the river and the food is delicious! The buddha bowls looked great but we went for the fried soy meat sando and plate with corn fritters and fries and was very happy with the result! The pita gave me that sandwich feeling i’ve been craving and it didn’t disappoint.

Pros: Fried soy meat, Location and view, Friendly staff

One of the best Vegan restaurants in Osaka

Overall, excellent food. Their karage is incredibly tasty. The soy ramen is one of the best ramens that I have ever tried. Fully recommended place!
On too of this, if you sit outside, you have an amazing view of the Tosahori river.

Pros: Tasty food, Excellent vegan ramen, Good views in outside seating area
