Western Style Breakfast

I love a good breakfast spot, and Optimus Cafe has really good choices!
Their French toast and Have A Good Day Plate are really delicious!
Their staff was a bit grumpy and chaotic though. They made me the wrong smoothie and took quite some time to remake it, and as I had wanted to drink that first, the rest of the food got quite cold. It was still delicious though.

Go for the view, good is average

Gorgeous spot to sit facing the river, I would go alone for the view. The food was tasty, they’d ran out of avo which was a shame but the food was decent. Not my fav but the view alone is worth going. Not the most flavourful food.

Serene location and very tasty

The Buddha bowl was lovely and the location on the water was very tranquil. The soy meat (side dish) was not the best, but the main course was great!

Bland taste

Unfortunately the food here wasn't as good as in other places in Japan. It was almost tastless and the portions were small as to the price. Also the restaurant was pretty dirty. They seem to have a great view of the river but the day we visited them, the terrace was blocked. I left the place quite disappointed.

Great Location and good food!

The river terrace is awesome, while the breakfast option could be more diverse and the portions somewhat larger. Overall, a good place to enjoy a vegan breakfast.

Pros: Terrace , Strictly vegan, Servers

Cons: Small potions

It is okay but i wouldn't come back

We had the Avo Toast with Orange Juice and the PB Toast with a Oat Milk Latte.
All for 2000 Yen.
The Coffee was not nice, so i wouldn't recommend it.
Also there is little seating options.

Great view, great food

Had a great mixed plate of breakfast. Server doesn't speak english, but ordering via website was no problem. The view is truly great and the food is really good, even creative. Portions could've been larger for my european stomach.

Pros: Great view, Great taste, Fair price

Cons: Portion size

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.

Pros: Food, View, Smoothies

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
