Green Street Cafe off Warner and Bolsa Chica (north HB)! It’s a bonus if you also like chicken & waffles, because they have the best. It’s a small spot less than a mile from the beach. I’ve never had a bad meal there.
I would recommend Rancho Viejo as a good Mexican place nearby. Green Tomato Grill and Freshco are both healthy-ish fast casual places with good breakfasts and lunch/dinner. Ham’n’scram is a great breakfast burrito place. I will also second Green Street Cafe! There are two taquerias at Springdale…
I usually like to go to a breakfast spot or Cafe alone. Green Street Cafe has great food but it gets busy sometimes. There are lots of places like that in and around hb, might be worth looking into :)
Idk about healthy but Mama’s is great for brunch. If you make your way down to pch and warner, riip has great pizza. Then down Warner about a mile is green street which is another great breakfast spot. And then further down Warner is Bolini’s il forno which is my favorite pizza in HB. Cash only though.
That’s all I really have for you.
