Well, for me the choice was fairly easy -- I have a DH who is Culinarily Challenged! One look at Blue Zoo menu and I could already envision his furrowed brow, the beads of sweat forming on his forehead as he read of dishes garnished with mango salsas, sprinkled with toasted fennel, doused in essence of truffle, accompanied by avocado puree... if a bubble could appear over his head, it would read, "BUT WHERE IS THE FOOD?"
On the other hand -- SHula's menu read like a 1st grade primer... Colossal shrimp cocktail, classic Caesar salad, double stuffed potatoes, fresh asparagus, and lest I forget, big ol slabs o' meat. I think he could handle that.
I think you would need more adventurous tastebuds for BlueZoo. Personally, I love new ideas and different tastes, and I would probably love Blue Zoo -- but I love my hubby more, so for his dining comfort, we're off to SHula's.
