I had their "premier sampler" on draft in Covington, LA. The Biere du Guarde was my least favorite. The others were good, especially the IPA. That is a fun place to go with good food; if you're traveling on I-10 it is worth the 5-mile detour.
I did not have the watermelon beer, nor would I sip it if offered. That sounds like an asthetically and philosophically flawed concoction.
