Spiral Diner, the kick-ass vegan restaurant in Oak Cliff, has more than just delicious veggie-monster-friendly meals: They have Oogave natural soda on tap. Oogave offers a variety of yummy flavors, including mandarin Key lime, cola and ginger ale. But none compare to their watermelon cream soda. It's sweet, pink, no-high-fructose-corn-syrup, all agave-sweetened hippie happiness. Watermelon cream soda from Oogave is about the best thing that this planet has to offer, non-alcoholic bev-wise, and it's pretty expensive if you buy it at Whole Foods in a bottle. So, when you're getting your herbivore on at Spiral Diner and you have access to free refills of the stuff, take full advantage of that situation, friends. Order your veggies, pass on the regular water and roll up to that self-serve Oogave soda fountain ready to chug some delicious watermelon-flavored agave angel nectar. Mmm.
