Review of Burger 21

I come to this location often for a GF burger 101 and GF fries & it is very good. Although they ask how you would like your burger cooked, I rarely have gotten how I've requested (medium). It is always cooked well done, which is disappointing but still doesn't sway me not to go. Not sure why they ask how I'd like it cooked if they are unable to execute my preference.
