First things first: B Spot has more than burgers. A few salad/sandwich options, and (important for me) non-beef burger options, both turkey and veggie. I got a custom made turkey burger with egg and avocado, and my girlfriend got the Gobbler. Fries aren't included with burgers, so we got a side order of them.
The burgers were thick (easily a 1/3 lb, probably more), hot, and at our table within 5 minutes. They were deliciously messy, but not so messy that you just end up eating it off your plate with a fork.
The fries weren't bad, but we didn't really have room for them. If I had to nitpick something, it would be that the sauces provided at the table aren't very good. I didn't feel a need to use them though; it's not worth subtracting a star.
