Cheeseburger Bobby's

So I'm meeting my brother for dinner tonight, something we try to do at least once a week, varying different places, or eating at home. So we going to Cheeseburger Bobby's tonight. I know I should have said, "Let's go someplace else", but it a favorite of ours and we both been watching what we've been eating. So I go look online to see what I can have and still make it with in my calorie zone. I can't find any nutrition information on their website or the web in general. I was just wondering if anyone has kinda found a good alternative to kinda use as rough estate on the calories.

We already agreed, not to add fries, I'm considering just a hamburger and no cheese. Thank goodness I still have a good bit of my calories for the day, b/c I was doing a healthier lighter breakfast and lunch/snack.
