I've never been to Hanna's, but I've been to Stubrik's and imho Mastro's is better. Mastro's is one of my favorite steakhouses. Their bone-in ribeye is probably the best I've had. Add in their seafood tower, signature mashed potatoes, and signature dessert, and you've got an awesome steakhouse. Corkage is high at $25, though.
