Comida rica, sitio precioso

La comida está muy rica y hay múltiples opciones veganas.
El precio está bien y el local en sí es precioso.
Hay terraza arriba al aire libre con mucha planta verde y la zona interior también es muy guay. Tiene un rollito decadente tipo Berlín.

Opción buena, mejorable

Muchas opciones plant based para desayunar y comer, la presentación bonita y el sitio amplio y agradable. El sabor algo soso y el precio elevado.

Love this cute place!

Super charming place, perfect for that Saturday’s brunch vibes with friend or just to enjoy by yourself. Really divine banan bread. The açai-bowl is really nice but could do with an improvement when it comes to the presentation. The coffee was alright…

Hair in the food

We found a black hair in our food, none of us have black hair. The respond from the waiter was just, you want another one?! It was so disgusting and the service so bad.
Actually the service from when we arrived was bad, we had to go to the counter because no one came to wait on our table, just to be told that we should wait at our table.

Not a place I’d recommend at all.

Pros: The seating

Cons: Hair in food, Service

Cosy Spot for a Relaxing Breakfast

A spacious and cosy place for breakfast or brunch. Service was quick and friendly. I had a delicious filled croissant, fresh granola, and a creamy, tasty smoothie — all wonderful. The place could be fully vegan, but either way, it’s definitely worth a visit.

Healthy and Fresh Lunch

Flax & Kale is a local chain that offers a variety of plant-based fare. They market themselves as a flexitarian restaurant and they truly were with 80% of the menu being plant-based while offering fish as well.

The restaurant itself is gorgeous. Well-lit, wide space, and beautiful calming aesthetic to take you away from the touristy Las Ramblas right nearby.

I went straight for Teresa's Favorite Kale Salad (€12) and their Mango & Avocado Tartar (€11), only to realize the latter was essentially already included in my salad. The large bowl of salad had a mix of kale (duh), tomatoes, sprouts, avocado, nori sheets, mango, and radishes. It was fresh, delicious, and much needed after a week of eating nonstop paella.

Service was friendly but a bit slow. We waited nearly 30 minutes for our food to come out even though it wasn't busy, but that may just be the Spanish culture.

Excellent lunch option

This was an excellent lunch option. I had the plant based caesar salad with falafel. It was delicious.

Mayoría de platos veganos y ambiente moderno

Restaurante flexitariano con una carta llena de platos veganos. Está bien tanto para una merienda como para una comida o cena. Me gusta mucho el local porque tiene varios ambientes, dos salas en la planta baja más otra sala y terraza en la planta superior. No es un sitio barato, pero la comida está muy buena y tiene una ubicación céntrica. Está muy bien para ocasiones especiales o para tomar algo. Recomiendo probar sus kombuchas porque tienen marca propia y saben muy bien.

Great vegan choice

This is a brand offering vegan dishes located in several locations in Barcelona.
They have a morning, lunch and dinner menu.
I was able to try the best plate of Hummus of my life, with vegetable balls and raisin, "Hummussimo" which caught my eye right away!
For dessert, I was able to try the two-texture choco chocolate, excellent!

Enjoyable meal

I love that everything is GF! Also, most items are vegan. They also serve some “fatty fish “ items like tacos. We had really great hummus and very tasty salad. The ambience is nice and service is good!

Pros: Gluten free, Tasty food , Extensive menu

Cons: All good

Inconsistent

Having read another comment saying the same, I thought service was odd - the waiter was hovering, taking our plates just as we were finishing, and didn’t crack a smile.
Had a passion fruit cake during the day which was amazing, so we’d come back for dinner.
Ribs were good - but possibly need something else on the side as they were quite sweet. My pad Thai was also alright, very light.
Dessert-wise, I had a pretty sour cheesecake, possibly it was even off. My partner’s cake was lovely though.

Meraviglioso pranzo all'aperto a gennaio

Locale molto carino e ben arredato. C'è la possibilità di mangiare in terrazza sotto il sole anche in inverno. Piatti molto particolari. Abbiamo preso un pad thai con fake chicken e delle fake ribs. Porzioni abbondanti. Buonissimi entrambi! Super consigliato! #Veganuary

Amazing experience

Absolutely loved this place and the food was so nice, would definitely come back for more. The waiters were very lovely and made us feel welcome 😊 the only downside is that our food was forgotten in the kitchen until we asked to check, but other than that really enjoyed everything.

Pros: Lots of interesting vegan options , Friendly staff, Nice cosy atmosphere

weirdest service ever

As all the other reviews have said, the food is great, delicious, yet super refreshing. but the service was absolutely bizarre. not dismissive or rude, but the waiters kept hovering and my friend and I felt like we were being watched all the time. My friend and I shared a muffin (which was delicious), as well as other things on their menu, and the waiters kept taking away our plates, even though we weren’t done. I had 5 bites left of my toast, and the waiter started taking my plate away without asking!! I am usually so relieved by the service in Spain, where waiters leave you alone until you call them and ask for the check—was not the case here. I’m not totally sure what to make of it—I guess I’d suggest to go, but make sure you are protective of your unfinished food, so a waiter doesn’t swoop in and take it before you are finished!

Pros: delicious, healthy food

Cons: terrible service

Would give 5* if I could!

Absolutely sensational meal and our favourite of the holiday so far. Service, atmosphere, restaurant all beautiful. Book the terrace if you can! The ribs and meatballs were spookily realistic, and their house wines are naturally vegan. A really special meal we loved every bite. My pad thai was nice however looking back I probably wouldn’t order it again, however the hummus, broccoli and ribs were all 10/10.

Pros: Lots of options, Beautiful decor and restaurant , Well priced vegan wine

We had lunch here on our trip in Barcelona

The venue is large, well laid out and spacious.

The food is wonderful. Really tasty, clever healthful dishes. We enjoyed the dumplings, Caesar salad and bbq ribs. All were excellent and thoroughly enjoyed

Would recommend and we are planning a dinner visit before we go home

Pros: Food, Venue, Quick

Cons: Slightly too business like service at times
