Even though those of us in the valley are blessed with all kinds of local brewery options, (Four Peaks, Sonora, Papago, etc.), sometimes I get a hankering to visit Gordon Biersch for one simple reason: garlic fries. I'll admit that all their food options, while good, scream out "I'm a menu item from a giant chain brewery" and lack that little something that makes it unique to your area.
Over the years I think that the quality of their beer has gone downhill. The only thing really drinkable here is the Marzen, along with a couple of their seasonal brews. As for plusses of this place, I'd really recommend sitting on the patio/terrace, which is great for sitting on and watching all the goings on happening on Mill. Another plus is the staff: HOT! Thank the lord for the close proximity to ASU and a great talent pool for hiring.
It may just be my tastes and likings, but Gordon Biersch is a bit too upscale for me. It's tough to get out of these without spending over $25 on dinner and a couple of beers. As far as breweries go, this is very family friendly, more so than the other options here in the valley.
