I don't know what it is about GB's Martzen, but it tears me up........in a good (or bad) way!! GB's microbrews are delicious and very strong! Be prepared!!
Happy hour at GB is excellent and always busy as hell! If you've been in Vegas for more than a few years you can count on running into a few friends during happy hour at GB.
The food is always good at GB, but like so many other restaurants they've added some cheap ingredients to some of their signature dishes. One glaring example of cheapening their dishes is the gorgonzola salad with pecan crusted chicken. The greens originally used in this salad were a fresh spring mix. It was awesome for a while. Now the salad is made with iceberg lettuce. Needless to say, the taste of this dish has suffered significantly!
GB's happy hour bar food menu is still very good. The Rib Eye with bleu cheese is likewise, excellent! But, if you're going to GB, the beer is definately the star!!
