I like the ones at Pecos Bills, because I love the fixin's bar. I could fill up on the mushrooms. If you like the unusual, try one at Raglan Road in DTD. I got one there that I swear had raisins, sliced ham, and a beef patty in it, along with all the other fixings. Sounds weird I know, but they were REALLY VERY good. They were also really huge. No way can one person eat a whole one.
Beaches & Cream has a reputation here on the Boards for good burgers, but I have yet to get one. I took my son and GD there in Jan '05 and after telling them how great the burgers were got a really strange look from my son. They were just plane old cheap soy filled DQ like burgers. I stayed at BWV in May '05 and decided to to give them another try. I again got a DQ quality burger. I finally asked the waitress about it and she told me that anytime they run out of burgers they use the ones from Hannah's. Oh! that explains it. Anyway I gave them one more chance this past January and again got a cheap, crummy DQ burger. I give up!
