I have had one meal from Whataburger, one from Drifters and found both to be good. Not oh my gosh good, but good.
I don't do McD unless I am on a road trip. The Mc' Rib was also in the 'it's ok' group. I rather have the egg McMuffin with sausage.
The only fries I like are from Chick fil-a, tater tots from Sonic are fine.

For me a simple fried burger at home on a toasted bagel + real cheese works best. Fresh tomato if I have it.

The green line grill for what it is worth had the better onion burger over all the common burger joints in town(Col Spgs).
