We ate at T-Rex on Saturday and HOB tonight. I have to say, we were all pleasantly surprised with the food at T-Rex. I really wasn't expecting much, but the food was very good. Our waiter was SUPER helpful and actually guided us in ordering, but the food was delicious. My mom and I got mahi-mahi, which was great. My husband got fish tacos, also great. And my dad got ribs, which he loved. The kids loved their meals too.
We also really liked HOB. We had the wings, calamari, and burgers. All very good. I would say that if you have young children, go with T-Rex. My girls LOVED it and keep asking to go back. It was definitely an experience for them (and us!). HOB was good but the overall experience for kids is nothing much.
I don't think one was particularly more expensive than the other, although we did have a $50 coupon to HOB from Restaurants.com, which helped. Hope this helps a little!!!
