Bob's Giant Burgers

I dropped by Bob's Giant Burgers last weekend again (for a burger, of course) - I have to say that while it is tasty, the quality of the beef is not that good; you can tell by sight and taste. (I suppose the good thing about In and Out's thin patties is that you don't see much, but I will try a visual inspection next time I go, whenever that may be.) Given the price of the burgers at BGB it is unlikely I'll go there again. So what other burger places are there in the Fremont Area?
